D) Glycolysis is considered to be an ancient metabolic system because it is the most efficient metabolic pathway for ATP synthesis. To obtain energy from starch and glycogen, the body must begin by. hydrolyzing both starch and glycogen to glucose. When proteins are used as a source of energy for the body, the proteins.
A culture of bacteria growing aerobically is fed glucose containing radioactive carbon and is then examined. During the citric acid cycle, radioactivity would first appear in.
B) The inner mitochondrial membrane plays a role in the production of pyruvate. The mitochondrial cristae are an adaptation that. increases the space for more copies of the electron transport chain and ATP synthase complexes. A mutant protist is found in which some mitochondria lack an inner mitochondrial membrane.
