Which type of mammalian cell does not carry out oxidative phosphorylation?
Correct answer: D. RBCs
- A. Cardiac muscle cells
- B. Liver cells
- C. Neurons
- D. RBCs
Explanation
RBCs have a biconcave shape and it lacks nucleus and mitochondria and hence many metabolic pathways such as oxidative phosphorylation. Instead, RBCs depend on the anaerobic conversion of glucose via pyruvate to lactate.

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.
