Which of the following types of mammalian cell does not carry out oxidative phosporylation?
Correct answer: A. Erythrocytes
- A. Erythrocytes
- B. Neuron
- C. Oxyntic cell
- D. Cardiac muscle cell
Explanation
Oxidative phosphorylation takes place in mitochondria. Erythrocytes (red blood cells) lack mitochondria, so they cannot perform oxidative phosphorylation and rely only on glycolysis for ATP production. Other cells like neurons, oxyntic cells, and cardiac muscle cells contain mitochondria and carry out oxidative phosphorylation.

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.
