(A) Statement $(A)$ is correct: The synthesis of $ATP$ from $ADP$ and inorganic phosphate in the presence of light is known as photophosphorylation.Statement $(B)$ is correct: Kranz anatomy is a specialized structure found in the leaves of $C_4$ plants,where mesophyll cells surround the bundle sheath cells.Statement $(C)$ is incorrect: During the Calvin cycle (biosynthetic phase),$NADPH$ is oxidized to $NADP^+$ to provide electrons for the reduction of $3-PGA$ to $G3P$. The reduction of $NADP^+$ to $NADPH$ occurs during the light-dependent reactions.Statement $(D)$ is incorrect: In a chlorophyll molecule,the magnesium ion $(Mg^{2+})$ is located at the center of the porphyrin ring,not in the phytol tail.Therefore,statements $(A)$ and $(B)$ are correct.
