What would be the effect of a mutation that enhances the activity of pyruvate dehydrogenase kinase?...
What would be the effect of a mutation that enhances the activity of pyruvate dehydrogenase kinase? O There will be a buildup of lactate as the cells turn to fermentation for their energy requirements. O There will be an increase in fatty acid production as the concentration of acetyl CoA increases. O There will be an increase in the activity of the citric acid cycle with the increased production of acetyl CoA. The cell will begin to convert acetyl CoA...

What changes in fatty acid metabolism would result from a mutation in the muscle carnitine acyltransferase I in which the mutant protein has lost its affinity for malonyl-CoA but not its catalytic activity? A. Fatty acid synthesis in the mitochondria and fatty acid oxidation in the cytosol could occur simultaneously. B. Fatty acid synthesis in the cytosol and fatty acid oxidation in the mitochondria could occur simultaneously. C. Synthesis of malonyl carnitine could only occur at high malonyl-CoA concentration. D....

What would be the effect of a mutation that replaced the alanine residue at point A in the structure with a threonine residue? - This would not affect the molecule and the mutant protein would be functional. - This would break the helix and form hairpin structures, that would make the mutant protein nonfunctional. - This would result in a partially unfolded protein, and the mutant protein would be nonfunctional. - This would break the helix near the Fe2 binding...

Why does acetyl CoA, a product of fatty acid catabolism, influence the pyruvate dehydrogenase complex (PDH),...
Why does acetyl CoA, a product of fatty acid catabolism, influence the pyruvate dehydrogenase complex (PDH), a control point in carbohydrate catabolism? When fatty acid breakdown is high, ADP is low and PDH is inhibited by phosphatase activity. When fatty acid breakdown is inhibited, PDH is inhibited by acetyl CoA due to phosphatase activity. When fatty acid breakdown is high, NADH levels drop, causing an increase in E2 activity. When fatty acid breakdown is high, PDH is inhibited by acetyl...

You recently joined a biochemistry research lab to study protein functions in diseases. In the lab, researchers have been working on a protein kinase, the enzyme that catalyzes the phosphoryl transfer reaction from ATP to the -OH group on serine or threonine residues of the target proteins. The researchers in the lab have found that a point mutation in the gene encoding the protein kinase leads to a change in one amino acid of the enzyme, which causes an increase...
