A molecule that is common to carbohydrate and lipid metabolic pathways and connects these two pathways metabolically is
A) glucose.
B) pyruvic acid.
C) acetyl coenzyme A.
D) glycogen.

Question

Quizplus · Accepted Answer

Acetyl CoA is a molecule that is involved in both carbohydrate and lipid metabolic pathways. It is formed from the breakdown of glucose during glycolysis and pyruvate oxidation, and it can also be formed from the breakdown of fatty acids during beta-oxidation. Acetyl CoA is an important intermediate in many metabolic processes, including the citric acid cycle, which is involved in both carbohydrate and lipid metabolism. Additionally, acetyl CoA can be used to synthesize fatty acids, which are important components of lipids. Therefore, acetyl CoA is the molecule that best connects these two pathways metabolically.
