Cellular respiration is carried out in:
Correct answer: B. Mitochondria
- A. Ribosome
- B. Mitochondria
- C. Chloroplast
- D. Golgi bodies
Explanation
Mitochondria are often referred to as the "powerhouses" of the cell because they are the primary sites of cellular respiration. These organelles have a double membrane and contain enzymes and other molecules necessary for the various steps of cellular respiration, such as glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain.

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.
