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?

A microbiologist compares ATP production in a bacterium growing with oxygen versus the same bacterium growing under anaerobic conditions using fermentation. The researcher observes that fermentation allows the bacterium to continue glycolysis but produces far less ATP because the Krebs cycle and electron transport chain are not used. Approximately how much ATP is produced per glucose molecule during bacterial fermentation?

A microbiology student compares aerobic respiration in a bacterial cell and a human liver cell. The student notices that both cells use an electron transport chain and ATP synthase, but the locations of these processes differ because bacteria lack membrane-bound organelles. Where does aerobic respiration primarily occur in a prokaryotic cell?
