Question

Consider the following statements regarding photosynthesis (a) ATP formation during photosynthesis is termed as photophosphorylation (b) Kranz anatomy pertains to leaf (c) Reduction of NADP to NADPH occurs during Calvin cycle (d) In a chlorophyll molecule magnesium is present in phytol tail. Of the above statements

• A. (a) and (b) are correct
• B. (c) and (d) are correct
• C. (a) and (c) are correct
• D. (a) and (d) are correct

Answer 1

Answer: (A)

(a) and (b) are correct

Answer 2

Reduction of $NADP^{+}$ to $NADPH$ occurs during non-cyclic Photophosphorylation of light reaction, while oxidation of NADPH takes place during Calvin cycle.
Tetraporphyrin 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.
