Question

Which of the following characteristic is similar to both cellular respiration and light dependent reactions of photosynthesis?

• A. Production of ATP
• B. Production of AMP
• C. Production of GTP
• D. Production of oxygen
• E. Use of carbon dioxide in synthesis reactions

Answer 1

Answer: (A)

Production of ATP

Photolysis of water is followed by transfer of its electrons to a zig-zag scheme of photosynthesis and drives formation of ATP during light reactions. Cellular respiration includes oxidation of glucose molecule and the released energy is stored in form of ATP at various steps. GTP is not produced during light reactions of photosynthesis but is produced in Kreb cycle of aerobic cellular respiration. Oxygen is a byproduct of light reactions but is consumed during electron transport chain of cellular respiration. Dark reactions of photosynthesis use carbon dioxide.

So, the correct answer is option A.
