What is the primary site of cellular respiration and ATP production in eukaryotic cells?
A. Ribosome
B. Endoplasmic reticulum
C. Mitochondrion✓ Correct Answer
D. Golgi apparatus
💡 Solution & Explanation
Mitochondria serve as the primary intracellular sites for aerobic cellular respiration, synthesizing adenosine triphosphate to satisfy cellular energy demands. Alternatives like ribosomes handle translation and protein assembly, while the endoplasmic reticulum manages lipid synthesis and membrane folding. These organelles contain their own ribosomes and DNA, supporting the endosymbiotic theory of cellular evolution.
