what can happen during the cycle of photosynthesis with increasing concentrations of Atrazine?
Answers
Answer:
By inhibiting photosynthesis, Atrazine kills plants. Photosynthesis, which is unique to living green plants, occurs when light energy becomes the chemical energy required for food production.
Simply stated, plants eventually die of hunger when food production stops. Atrazine selectively kills unwanted plants (weeds) competing with suitable plants for water and nutrients (crops, turfgrass). It is thus a beneficial tool for both farming and urban plants.
Explanation:
In Texas maize and grain sorghum production, Atrazine is the most often used herbicide. In several "weed and feed" preparations for domestic plowing and commercial turf-grass weed control, it is also often found as an active ingredient.
With its broad use, atrazine has been identified in minute concentrations in Texas ground and surface waterways. Because of this, it is crucial to understand atrazine behavior in the environment and the potential for harmful impacts on human and animal health and on other non-target organisms.

Predict what will happen to the concentration of pyruvate, NADH and H+ when the Krebs cycle is stopped by arsenic
Answers
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.
What is Kreb's cycle?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.

which property has not been observed for membrane proteins being degraded for energy during biological pathways
Answers
Answer:
energy storage
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.

The scientists mapping the SNPs in the human genome noticed that groups of SNPs tended to be inherited together, in blocks known as haplotypes, ranging in length from 5,000 to 200,000 base pairs. There are as few as four or five commonly occurring combinations of SNPs per haplotype. Integrating what you've learned throughout this chapter and this unit, propose an explanation for this observation.
Answers
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.

Using sophisticated molecular cloning techniques, you have isolated the genes for two serotonin transporters, called TransA and TransB, which are expressed in these neuronal cells. A preliminary immunofluores- cence localization of fixed and permeabilized cells found very bright staining of TransA at the nerve cell plasma membrane and little staining elsewhere. TransB, in contrast, stained only very faintly at the nerve cell plasma membrane, but there was intense staining within the cytosol.
Required:
In which subcellular membrane or organelle would you expect most of the TransB to be found? Explain your answer.
Answers
Answer:
Vesicles
Explanation:
Serotonin is a neurotransmitter that transports signals or messages between neurons.
Most neuronal cells have vesicles in their interior, which are organelles that store neurotransmitters for exportation -by exocytosis- or from recycling -by endocytosis-. These vesicles also protect the neurotransmitter from the enzymatic action.
Vesicles form in the cellular soma, from where they are transported to nervous terminals. Once the vesicle releases the neurotransmitter to the intercellular space, their membrane remains available in the plasmatic membrane to be reused.
The neurotransmitter concentration in the vesicle interior is related to the storage system and the transport system. There are specialized transporter proteins in the vesicle membrane that are involved with the introduction of the molecule to the organelle.
In the exposed example, transporter Trans B might be located in the vesicle membranes, and hence could be found in the cytosol of the cells.

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

Hemophilia is an X-linked recessive condition in which blood does not clot properly. Queen Victoria of England had one allele for hemophilia. Most of her male descendants had the disorder, but few females had it. Why did hemophilia occur more frequently in Queen Victoria’s male descendants?
Answers
Answer:
Because hemophilia is an X-linked recessive condition.
Explanation:
As the problem states, hemophilia is an X-linked recessive condition.
Meaning that in Queen Victoria's female descendants (coded XX) which inherited the Queen's one allele, for hemophilia to appear in them it would be necessary to inherit another hemophillia-carrying allele from the father.The Queen's male descendants (coded XY) would always manifest hemophilia if they inherited the Queen's hemophilia allele, as they possesed only one X gene.When a neuron is stimulated and sodium channels open, the process of has begun.

Answers
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.
how digestion happens in human
