The inner membrane of a mitochondrion is very selective about what it allows to leave the organelle. One molecule that regularly passes out of a mitochondrion is:
Correct answer: A. ATP
- A. ATP
- B. Pyruvic acid
- C. Glucose
- D. Citric acid
Explanation
ATP is synthesised within the mitochondrion during cellular respiration, and it can leave the mitochondrion to provide energy for cellular processes elsewhere in the cell.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
