Which cellular organelle is primarily responsible for aerobic cellular respiration and the synthesis of adenosine triphosphate (ATP)?
Answer and explanation
Correct answer: A. mitochondrion
- Step 1: Cellular respiration occurs in the mitochondria where pyruvate is oxidized through the Krebs cycle and oxidative phosphorylation. Step 2. This generates the majority of ATP energy for cellular metabolic activities. Answer: mitochondrion. Why not the others: Chloroplasts perform photosynthesis; ribosomes synthesize proteins; Golgi apparatus packages and secretes macromolecules.
