Question

Select the process associated with the structure which is represented by arrows.

• A. Carbon fixation
• B. Photochemical reactions
• C. Anaerobic respiration
• D. Aerobic respiration
• E. Oxygen fixation

Answer 1

Answer: (D)

Aerobic respiration

The image shows cristae of mitochondria, which have embedded electron transport chain and serve as a site for aerobic respiration. Aerobic respiration is the breakdown of sugar/other food substances, in presence of oxygen to released energy. It includes glycolysis, kerb cycle and electron transport chain. Carbon fixation and photochemical reactions are related to photosynthesis and occur in the chloroplast. Anaerobic respiration occurs in cytoplasm only. The correct answer is D.
