functions of insulin

Answers

Insulin is a hormone that controls blood glucose (sugar) levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Which of the following is an example of an enzymatic cycle?

Answers

Answer:

Catabolism

Explanation:

The process of catabolism degrades the bacterial and fungal enzymes into simple inorganic molecules.

A substance, without being a reactant, which speeds up a chemical process is referred to as a catalyst. Enzymes are known as catalysts for biological reactions in living organisms. Although ribonucleic acid (RNA) molecules behave as enzymes, they are usual proteins. Enzymes.

Enzymes carry out the essential role of reducing the activated energy of a reaction — that is, the amount of energy needed to start the process. Enzymes work by attaching and retaining reactant molecules so that the chemical bonding and bonding activities are carried out more easily.

DNA is a nucleic acid involved in heredity, or the passing down of genetic traits from one generation to the next. DNA consists of four different types of nucleotide monomers.Which part of the nucleotides' structure is responsible for the incredible variation that exists amongst all types of organisms

Answers

Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:

-Adenine is paired with Thymine (think of A for apple and T for tree)

-Cytosine is paired with Guanine (think of C for car and G for garage)

You are studying an enzyme that is inactivated by phosphorylation and create a mutant in which the threonine that is normally phosphorylated is replaced with glutamate. Predict the impact of this change on the activity of this enzyme. Group of answer choices

Answers

Answer:

always active  

Explanation:

Phosphorylation is a posttranslational modification that consists of the addition of phosphate groups to specific amino acids on the protein. Phosphorylation acts as a molecular switch for proteins that are phosphorylated (i.e., in some situations phosphorylation acts to activate protein function, whereas in other situations phosphorylation can inactivate protein function). Phosphorylation modifies the three-dimensional structure of the protein, thereby affecting, for example, the accessibility of the active site of a phosphorylated enzyme to its substrate. Phosphorylation can occur only at the side chains of three amino acids: Serine, Threonine and Tyrosine. In this case, the enzyme is inactivated by phosphorylation on the Threonine residue, so it is expected that the mutant enzyme cannot be phosphorylated, remaining in an active state.

What is DNA replication?

Replication is the procedure by which the DNA of the genetic code is copied in cells.

Before dividing, a cell must duplicate (or replicate) its a whole genome so that each eventually results daughter cell has its own entire genome.

The DNA replicates itself multiple times during the process of replication. It is a biological polymerization that goes through the steps of commencement, elongation, and termination.

The reaction is catalyzed by enzymes. The main enzyme in the process of replication is DNA Polymerase.

DNA replication occurs in eukaryotic cells' interphase nuclei. At the S-stage (synthesizing) of the cell cycle, DNA replication occurs prior to mitosis.

Thus, the correct option is C.

Describe the disadvantages of an open circulatory system relative to a closed circulatory system.

Explanation:

The disadvantage of a closed circulatory system is that with the blood always contained in vessels, it's under higher pressure.

Open circulatory systems are low-pressure systems that cannot meet the needs of a fast metabolism.

Answers

Answer:

The CRISPR-Cas9 genome editing system can be used to edit genes and correct mutations associated with inherited diseases. However, this technology also has the potential to edit genes in germline cells in order to irreversibly modify the human species and the natural evolution of life

Explanation:

The CRISPR-Cas9 (Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9) system is a natural prokaryotic defense system used by bacteria to defend against invading DNA. In the laboratory, the CRISPR-Cas9 system has been repurposed to create a versatile genome-editing tool that allows us to modify the genome of mammalian cells in a targeted fashion. The CRISPR-Cas9 is a simple gene-editing tool that consists of a single guide RNA (sgRNA) that guides the Cas9 enzyme to the exact genomic location where Cas9 needs to make a cut, which is then repaired by different DNA repair mechanisms. During DNA repair, nucleotides can be replaced and/or deleted, thereby producing desired genomic modifications. The CRISPR-Cas9 has an enormous potential to repair mutations in genes associated with inherited genetic disorders and cancer (i.e., oncogenes might be reversed in vivo by using this technology). However, the CRISPR-Cas9 genome editing system is also a subject of concern due to its dual use. For example, this technology can be used to modify the genome of germline cells by inducing mutations that can be passed across generations, thereby irreversibly modifying human DNA and altering the normal course of evolution.

Formation of compound is a change in chemical reaction and the components of compound are mixed in a fixed proportion.

Two major types of compounds are covalent and ionic compounds.

Covalent compounds refers to formation of covalent bond among two nonmetals, like water or methane. These molecules are neutral and weak.

When metal react with non metal it form Ionic compounds, are held together by opposite charges, so the bond is stronger than covalent compound.

Biomagnification is when toxins / heavy metal are present in small amounts in fish, but accumulate as you move into higher trophic levels. This is one reason why it can be toxic for humans to eat tertiary or quaternary consumers, such as swordfish, shark, etc.

Biomagnification refers to the presence of higher concentration of chemical toxins as a result of the accumulation of toxins in organisms.

What is biomagnigication?

Biomagnification is best explained as a condition in which the chemical concentration of a toxin is amplified in an organism compared to the environment in which the organism is found.

Biomagnification usually is observed as one goes higher in the trophic levels of organisms.

For example, chemical pollutant found in water may be present at tolerable levels. However, in organisms, living in the water, the concentration of the pollutant is higher as these organisms accumulate these toxins in their tissues.

Therefore, biomagnification refers to the accumulation of toxins in organisms higher than found in their environment.
