A biology student is tracing the complete breakdown of glucose during aerobic respiration in a bacterial cell. The student correctly identifies that glucose is first split into smaller molecules, then additional energy is extracted through a cyclic pathway, and finally most ATP is generated through membrane-associated electron carriers and ATP synthase. Which sequence correctly represents the order of the major stages of aerobic respiration?

A microbiologist studies an enzyme-catalyzed reaction in a bacterial cell and measures the amount of enzyme present before and after the reaction. The results show that the enzyme remains unchanged in quantity and can catalyze multiple rounds of the same reaction without being consumed. Which statement best explains this observation?
