Question

Consider the following statements regarding photosynthesis:

A. ATP formation during photosynthesis is termed photophosphorylation.

B. Kranz anatomy pertains to leaf.

C. Reduction of NADP⁺ to NADPH occurs during the Calvin cycle.

D. In a chlorophyll molecule, magnesium is present in the phytol tail

Of the above statements,

• A. C and D are correct.
• B. A and B are correct.
• C. A and C are correct.
• D. B and C are correct.
• E. A and D are correct.

Answer 1

The correct option is B

A and B are correct.

ATP and NADPH are formed during the light reaction phase (photophosphorylation), which is used during the dark reactions for the fixation of CO₂ and the synthesis of sugars.

Kranz anatomy is a specialised anatomy of the leaves of C₄ plants where the vascular bundle is surrounded by bundle sheath cells, which in turn are surrounded by mesophyll cells.
