Cellular respiration is also called:
Correct answer: B. Biological oxidation
- A. Internal respiration
- B. Biological oxidation
- C. Organismic respiration
- D. Both A and B
Explanation
Cellular respiration is best described as biological oxidation. This process involves the breakdown of organic compounds, such as glucose, in the presence of oxygen to produce ATP, which is the main energy source for cellular activities. Internal respiration is not appropriate because it refers to the exchange of gases between the blood and body cells, not the energy-producing biochemical reactions within cells. "Organismic respiration" is a broader term that includes all aspects of breathing but does not specifically focus on cellular-level processes. Therefore, the correct term for cellular respiration is biological oxidation.

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.
