Which of the following molecules are considered key molecules at metabolic crossroads?

Question

Quizplus · Accepted Answer

Glucose-6-phosphate, pyruvic acid, and acetyl CoA are all key molecules at metabolic crossroads. Glucose-6-phosphate can enter either glycolysis or the pentose phosphate pathway, pyruvic acid can enter either aerobic respiration or fermentation, and acetyl CoA can enter either the citric acid cycle or fatty acid synthesis. ATP and lactic acid are important molecules in metabolism, but they do not represent metabolic crossroads. Acetone and beta-hydroxybutyric acid are ketone bodies produced during low-carbohydrate diets or in uncontrolled diabetes and are not considered key metabolic crossroads.
