Chapter 25, Problem 13CP
Summary Introduction
To determine:
The products that are likely to form when a cell accumulates more acetyl-CoA than it can metabolize in the citric acid cycle.
Introduction:
Acetyl CoA is synthesized in the mitochondria by many reactions like the oxidative phosphorylation of pyruvic acid, and by the catabolism of some amino acids and by beta oxidation of fatty acids. It participates in many reactions of carbohydrate and the lipids
