Which organelle is required for aerobic respiration?
Correct answer: B. Mitochondria
- A. Plastids
- B. Mitochondria
- C. Endoplasmic Reticulum (ER)
- D. Nucleus
Explanation
Mitochondria are often referred to as the powerhouse of the cell because they are the sites of aerobic cellular respiration, a process that generates ATP, the energy currency of the cell. Unlike plastids, which are involved in plants' photosynthesis and food storage, or the Endoplasmic Reticulum, which is involved in the synthesis of proteins and lipids, mitochondria specifically facilitate the conversion of oxygen and nutrients into energy. The nucleus, while crucial for controlling cellular functions and containing genetic information, does not play a role in aerobic respiration.
