Q. Consider the following statements regarding photosynthesis. I. ATP formation during photosynthesis is termed as photophosphorylation. II. Kranz anatomy pertains to leaf. III. Reduction of $NADP^{+}$ to NADPH occurs during Calvin cycle. IV. In a chlorophyll molecule, magnesium is present in phytol tail.
A) I and II correct
B) III and IV are correct
C) I and III are correct
D) I and IV correct
Explanation
Reduction of $NADP^{+}$ to $NADPH$ occurs during non-cyclic Photophosphorylation of light reaction, while oxidation of NADPH takes place during Calvin cycle. Teporphyrin ring of chlorophyll a flat, square, structure of alternating single and double bonds containing four smaller pyrrole rings with a magnesium atom at the centre.
