Question

Quizplus · Accepted Answer

Glucose, amino acids and fatty acids can all be used as substrates for ATP production in different metabolic pathways. Glucose is the primary substrate for ATP production in glycolysis and the citric acid cycle. Amino acids can be converted to glucose in gluconeogenesis or can be directly used in the citric acid cycle. Fatty acids are broken down through beta-oxidation to produce acetyl-CoA for the citric acid cycle. Therefore, all three can be used for ATP production depending on the metabolic needs of the organism.
