Water releases protons, and twelve water molecules will release:
Correct answer: B. 12H+
- A. 24H+
- B. 12H+
- C. 6H+
- D. 1H+
Explanation
Each water molecule can release only one proton when it ionises. Therefore, twelve water molecules will release a total of 12 protons. Options suggesting fewer or more protons, such as 1, 6, or 24, are incorrect because they either underestimate or overestimate the number of protons released.

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.
