Explanation:

Membrane proteins are proteins that are either form part of or interact with cell membranes. Based on their interactions, membrane proteins can be categorized into integral proteins, which are a permanent part of a cell membrane, and peripheral proteins, which adhere temporarily to the cell membrane. Membrane proteins play many critical functions, for example, 1-they are involved in the passive and active transport of substances across cell membranes, 2-act as enzymes that catalyze chemical reactions, 3-act as receptors that bind specific molecules (such as hormones or neurotransmitters) in order to activate signaling cascades, 4-mediate communication between cells, 5-provide a mechanical link between the extracellular matrix and the cytoskeleton, etc.

Answer: Pyruvate would increase, NADH would decrease, and intermembrane H+ would decrease as well.

Explanation:

Glycolysis would raise pyruvate, but the Krebs Cycle would not produce NADH, decreasing it. No protons (H+) will be pushed into the intermembrane gap, lowering its H+ content and raising its pH.

The tricarboxylic acid (TCA) cycle, commonly referred to as the Krebs cycle or the citric acid cycle, is the primary route that cells use in order to acquire energy and is an essential component of aerobic respiration. The cycle transforms the oxidative potential of acetyl coenzyme A (acetyl CoA) into the reductive potential of nicotinamide adenine dinucleotide (NADH).

The synthesis of ATP via the Krebs cycle is disrupted when arsenic is present because it prevents pyruvate from being converted into acetyl coenzyme A (acetyl-CoA). In addition to the effects described above, arsenic also prevents glucose uptake at the cellular level, as well as gluconeogenesis, the oxidation of fatty acids, and additional acetyl-CoA formation.

Answer:3/4

Explanation:4 possibilities, 3 dominant

If a pigmented and non-pigmented organism mate and produce a pigmented organism, which mate again and produce non-pigmented organisms, the probability that the next offspring will be pigmented is ¾ as P is the dominant, pigment-producing allele.

The association between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the additional allele, known as the recessive one, is concealed.

If one is in charge, the other must be recessive. Then it is referred to as recessive. A dominant gene, or dominant form of a gene, is a specific variant of a gene that expresses itself more powerfully on its own than any other version of the gene that the individual is carrying—in this example, the recessive—for a variety of reasons.

Now, it mainly refers to patterns of inheritance typically used in combination with a Punnett square, where if a person has two copies of a gene and one is shown to frequently be passed down from one generation to another, it is referred to as dominant.

According to biochemistry, what is happening in this situation is that the genetic variant may, for a variety of reasons, cause a cell to perform a very advantageous or very disadvantageous function that the other version of the gene cannot cover up or counteract.

Therefore, the probability that the next offspring will be pigmented is ¾ as P is the dominant, pigment-producing allele.

Answer:

A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a hapten that binds to blood proteins, causing a strong immune response.

Explanation:

Low molecular weight chemicals can bind to antibodies, but cannot activate B lymphocytes by themselves (they are not immunogenic). To generate specific antibodies to these small chemicals, immunologists typically bind them to macromolecules prior to immunization. In these cases, the chemical is called a hapten. Penicillin G is a typical hapten that tends to covalently bind to lysine residues both in solution and in protein-bound cells. Penicillin is a drug that behaves as a hapten, since the beta-lactam ring under physiological conditions opens and reacts with the lysine residues of proteins, forming a complex that is the main antigenic determinant of penicillin and other beta-lactams and is capable of to stimulate responses mediated by antibodies or by T cells.

Cell: A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology.

Atom:  atom is the smallest component of an element, characterized by a sharing of the chemical properties of the element and a nucleus with neutrons, protons and electrons. The protons and the neutrons reside in the nucleus.

whats the difference between atom and cell?

function wise atoms take part in every chemical reaction while cells are responsible for the development and growth of living existences. Atoms do not have life. They do not need food, water, and they do not reproduce. Cells are alive. Cells consume food and water and can reproduce. Atoms construct molecules and Cells make tissues for organs.

Answer:

1. Phosphatases hydrolyze key phosphorylated residues.

Explanation:

Receptor Tyrosine Kinases (RTKs) are high-affinity transmembrane protein receptors that bind to a wide variety of ligands (e.g., growth factors, cytokines, hormones). These receptors (RTKs) have a transmembrane domain and therefore these proteins act as membrane receptors, as well as exhibit catalytic activity. The intracellular C terminal region of RTKs contains catalytic domains responsible for both autophosphorylation and tyrosine phosphorylation of their protein substrates. Moreover, Protein Tyrosine Phosphatase (PTPs) are critical enzymes that remove phosphate groups from tyrosine residues in different substrates (including RTKs), thereby regulating key signaling pathways such as cell proliferation, cell differentiation, and cell-cell adhesion.

Answer:

SNPs have shown that only 0.1 % of DNA sequences are different in the human genome between different individuals, thereby all the inherited phenotypic variation observed in our species is associated with only 0.1 % of differences at the genome level  

Explanation:

Haplotypes are block-like sequences of DNA that are inherited together due to low recombination rates. Moreover, single-nucleotide polymorphism (SNP) mapping is a very useful methodology used to map the site of SNP mutations (i.e., SNP variants). In this regard, it has been observed that there are approximately 10 million common SNPs in the human genome. These SNPs contribute to the wide range of phenotypic variation observed in human populations for different traits (e.g., eye color, hair, weight, height, etc). Moreover, researchers have determined that SNPs can be clustered into haplotypes, thereby haplotypes can be accurately sampled by as few as approx. 300,000 selected SNPs, which are sufficient to represent all of the genetic variation across different human genomes.

neurotransmitters are often reffered to as the body's chemical messangers. They are the molecules used by the nervus system to transmit messages between neurones, or from neurones to muscles. Communication between two neurones happens in the synaptic cleft (the small gap between the synapses of neurones).

Answer:

B. an amino acid can be encoded by several codons

Explanation:

The genetic code refers to the set of rules that govern how the four nitrogenous bases (A,U,G,C) is arranged to form amino acids. The genetic code is a collection of all the CODONS formed. There are different characteristics of the genetic code and one of them is its REDUNDANCY.

Since there are 4 nitrogenous bases combined in three's to form a codon i.e. 4³, there are 64 possible codons that could form 20 maximum amino acids. This means that there are more codons in relation to amino acids. Hence, more than one codon can encode an amino acid, and this is referred to as REDUNDANCY of the genetic code.

For example, LEUCINE amino acid is encoded by 6 codons as follows: UUA, UUG, CUU, CUC, CUA, CUG.

Answer:

There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Answer:

- When a neuron is stimulated and sodium channels open, the process of depolarization has begun.  

- Structures of the nervous system surrounding, but not part of the central nervous system are part of the peripheral nervous system

- Two consecutive neurons communicate at a synapse, where they physically come together.  

- Endorphins are a group of natural chemicals that reduce the perception of pain.  

- Supporting cells of the nervous system are collectively called neuroglia

- When potassium channels have been open long enough to go below resting membrane potential, hyperpolarization has occurred.

Explanation:

Neurons undergo depolarization in response to diverse stimuli (e.g., heat, light, electrical, chemical, etc). The depolarization occurs when sodium (Na+) ions pass through specific channels  (i.e., open voltage-gated Na+ channels) into a neuron, which causes an increase in the positivity of membrane potential. On the other hand, hyperpolarization occurs when potassium (K+) channels remain open and Na+ channels reset, thereby producing an increase in negativity of membrane potential. The peripheral nervous system (PNS) is composed of the cranial nerves, spinal nerves, peripheral nerves, and neuromuscular junctions, which connect the Central nervous system (CNS) to the organs, limbs, and skin. Endorphins (e.g., serotonin) are polypeptides secreted by the pituitary gland and CNS to relieve stress and pain. Neuroglia refers to a class of neural cells that have ectodermal (e.g., astroglia, peripheral glial cells) or mesodermal (e.g., microglia) origins. Neuroglia cells are involved in diverse roles, including, among others, the formation of the blood-brain barrier, homeostatic support, provision of nutrients for neurons, structural support to nerve cells, etc.

Answer:

Tibia and fibula. Tibia (medial bone)

Explanation:

The tibia is the medial bone of the lower leg (it is the second-largest bone next to the femur), whereas the fibula is the lateral bone of the lower leg. The tibia functions to transmit the majority of the force in the lower leg. The tibia articulates at the proximal end with the femur and fibula; where this bone (tibia) articulates at the distal end with the fibula and the talus bone of the ankle. The tibia and fibula are connected via an interosseous membrane, which is a thin sheet of connective tissue that spans the space between two bones.
