In the pedigree that is shown, which represents Irene's allele combination?
Greeley [361]

The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is X^{H} X^{H} .

Pyruvate dehydrogenase is regulated by feedback inhibition and covalent modification. Which molecules inhibit the pyruvate dehyd
Oksi-84 [34.3K]

ADP, NAD+, CoA-SH, and pyruvate are the molecules that inhibit the pyruvate dehydrogenase complex.

<h3>What is pyruvate dehydrogenase complex?</h3>

PDC3 triggers the oxidative decarboxylation of pyruvate, resulting in the creation of acetyl-CoA, CO2, and NADH.

The PDC plays a crucial role in the oxidation of glucose by connecting the glycolytic pathway to the tricarboxylic acid cycle's oxidative pathway.

ADP, NAD+, CoA-SH, and pyruvate all inhibit it. PDK prevents glycolysis from being coupled to GO by inhibiting its target enzyme PDH.

Thus, the answer is ADP, NAD+, CoA-SH, and pyruvate .
