Is the phenotype that corresponds to the HbS allele harmful, beneficial, or both?
horrorfan [7]

Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles.

<h3>What is phenotype?</h3>

Phenotype is referred to as the expressed trait that is caused by a certain combination of alleles. We will recall that the HbS allele is responsioble for the anemia that results from sickle shaped red blood cells.

This phenotype is both harmfull and benefical in the sense that it leads to the agglutination of the red blood cells in individuals that have this phenotype and eventual crisis. Also, it is beneficaila in that nthose who possess this phenotype do not suffer from malaria in the tropics.

Which enzyme(s) involved in fatty acid synthesis utilize ATP? Select all that apply.
GREYUIT [131]

Answer:

a. Acetyl CoA carboxylase  

Explanation:

Much of the fatty acids used by the body is supplied by the diet, excessive amounts of carbohydrates and protein obtained from the diet can be converted to fatty acids and stored as triglycerides. Fatty acid synthesis occurs mainly in the liver and mammary glands, and to a lesser extent in adipose tissue and kidney, the process incorporates acetyl CoA carbons into the forming fatty acid chain using ATP and NADPH.

The acetyl portion of acetyl CoA is transported to cytosol as citrate, produced by condensation of oxaloacetate and acetyl CoA, the first reaction of the citric acid cycle, this occurs when the concentration of mitochondrial citrate is high, observed when there is a high concentration of ATP and isocitrate dehydrogenase is inhibited.  The increase of citrate and ATP favors the synthesis of fatty acids, since this pathway needs both. Acetyl CoA should be converted to malonyl CoA. Carboxylation is catalyzed by acetyl CoA carboxylase and requires ATP, this reaction is the regulated step in fatty acid synthesis: it is inactivated by products, malonyl CoA and palmitoyl CoA, and activated by citrate, another regulatory mechanism is reversible phosphorylation of enzyme, which makes it inactive due to the presence of adrenaline / glucagon

What is the end result of cytokinesis from a cell undergoing mitosis?
IRINA_888 [86]

The end result of cytokinesis indicates the two cells with identical copies of DNA arise from a single parental cell.

<h3>What is Cytokinesis?</h3>

Cytokinesis may be defined as the process of separation of the cytoplasm at the end of mitosis.

Cytokinesis is the phase of mitosis which involves the overall division of cytoplasm and the construction of two copies of cells with identical DNA content.

It occurs after the process of karyokinesis, which results in the formation of two daughter cells from a single parental cell.

Therefore, it is well described above.
