Name the molecule that is common to carbohydrate and lipid metabolic pathways and connects these two pathways metabolically.
A)Glucose
B)Pyruvic acid
C)Acetyl coenzyme A
D)Glycogen

Question

Quizplus · Accepted Answer

Acetyl coenzyme A is a common molecule between carbohydrate and lipid metabolic pathways. In carbohydrate metabolism, glucose is broken down to pyruvic acid, which is then converted to acetyl CoA. In lipid metabolism, fatty acids are broken down into acetyl CoA. Therefore, acetyl CoA is the link between these two pathways. Glucose (A) and glycogen (D) are primarily involved in carbohydrate metabolism, while pyruvic acid (B) is an intermediate product in carbohydrate metabolism.
