Question

Which of the following statement is false about photosynthesis?

• A. Enzymes required for carbon fixation are located in grana of chloroplasts.
• B. In green plants, both PS I and PS II are required for synthesis of NADPH + H${}^{+}$.
• C. Electron carriers of photophosphorylation are located on thylakoid membranes.
• D. Photosynthesis is a redox process in which water is oxidized and CO${}_2$ is reduced.

Answer 1

Answer: (A)

Enzymes required for carbon fixation are located in grana of chloroplasts.

A) Enzymes require for carbon fixation are present inside the mesophyll cells.

B) NADPH is synthesised during non-cyclic photophosphorylation which involves both PS I and PS II.

C) The electron carriers (cytochromes b and f) are present on the thylakoid membrane.

D) Carbon dioxide is fixed and reduced and water is oxidised into a proton and oxygen during photosynthesis.

So the correct answer is 'Enzymes required for carbon fixation are located in grana of chloroplasts.'
