During cellular respiration, acetyl CoA accumulates in which location?

• Mitochondrial Matrix
• mitochondrial outer membrane
• mitochondrial inner membrane
• mitochondrial intermembrane space

During aerobic respiration, electrons travel downhill in which sequence?

• food � citric acid cycle � ATP � NAD+
• food � NADH � electron transport chain � oxygen
• glucose � pyruvate � ATP � oxygen
• glucose � ATP � electron transport chain � NADH

The primary role of oxygen in cellular respiration is to

• yield energy in the form of ATP as it is passed down the respiratory chain.
• act as an acceptor for electrons and hydrogen, forming water.
• combine with carbon, forming CO2.
• combine with lactate, forming pyruvate.
