Question

In animal cells, glycolysis and gluconeogenesis are regulated to ensure that both processes are reciprocally active. This regulation involves each of the following compounds except

A) NADH.
B) fructose-2,6-bisphosphate.
C) AMP.
D) acetyl CoA.
E) cAMP.

Answer 1

cAMP does not directly regulate glycolysis or gluconeogenesis, making it the compound that is not involved in the reciprocal regulation of these metabolic pathways in animal cells.

Step-by-step explanation:

Regulation of Glycolysis and Gluconeogenesis

In animal cells, glycolysis and gluconeogenesis are essential metabolic pathways that are tightly regulated to prevent the simultaneous activation of these opposing processes. Each pathway is controlled by various allosteric effectors and co-factors that respond to the energy needs of the cell.

The regulation involves several compounds, but not all of them participate in this reciprocal regulation. Compounds such as NADH, fructose-2,6-bisphosphate, and AMP are known to regulate these pathways. Acetyl CoA also has a regulatory role; however, cAMP does not directly regulate glycolysis or gluconeogenesis. Therefore, among the options provided, cAMP is the compound not involved in the reciprocal regulation of these metabolic pathways.
