Consider the following statements regarding photosynthesis and state ...
Photosynthesis

I. ATP formation during photosynthesis is termed photophosphorylation.
II. Kranz anatomy pertains to leaf.
III. The reduction of NADP to NADPH occurs during the Calvin cycle.
IV. In a chlorophyll molecule, manganese is a metal ion.

Explanation:
I. ATP formation during photosynthesis is termed photophosphorylation. This is a correct statement. Photophosphorylation is the process of converting light energy into chemical energy in the form of ATP (Adenosine triphosphate).

II. Kranz anatomy pertains to leaf. This is a correct statement. Kranz anatomy pertains to the arrangement of cells around the leaf veins in plants with C4 photosynthesis. This arrangement helps in the efficient fixation of CO2.

III. The reduction of NADP to NADPH occurs during the Calvin cycle. This is a correct statement. NADP+ (Nicotinamide adenine dinucleotide phosphate) is reduced to NADPH (Nicotinamide adenine dinucleotide phosphate) during the light-independent reactions of photosynthesis, also known as the Calvin cycle.

IV. In a chlorophyll molecule, manganese is a metal ion. This is an incorrect statement. In a chlorophyll molecule, magnesium is a metal ion. Manganese is not present in the chlorophyll molecule.

Therefore, the correct options are (A) I and II are correct.
