Chemiosmosis requires a membrane, a proton pump, a proton gradient and ATPase. B, C, D, E, I, J, K

The products of light reaction are ATP, NADPH and O 2 . A, B, D, F, H, I, K

The acceptor molecule of CO 1 in dark reaction is a 5-C aldehyde sugar-RuBP. B, D, E, F, G, H, J

The fixations of 6 molecules of CO 2 and 6 turns of the cycle are required for the removal of one molecule of glucose from the Calvin cycle pathway. (E) For every CO 2 molecule entering the Calvin cycle, 2 molecules of ATP and 2 of NADPH are required. (F) C 4 plants have a special type of leaf anatomy, tolerate higher temperatures and lack a process of photorespiration and have greater productivity of biomas. (G) Small cells around the vascular bundles of the C 4 pathway plants are called bundle sheath cells and the leaves which have such anatomy are said to have kranz anatomy. (H) ‘Kranz’ means wreath and is a reflection of the arrangement of cells. (I) C 4 pathway has been named Hatch and Slack pathway. (J) In C 4 plants, the primary CO 2 acceptor is a 3-C molecule PEP and is present in the bundle sheath cells. (K) In C 4 plants, mesophyll cells lack RuBisCO enzyme. The C 4 acid OAA is formed in mesophyll cells. Choose the correct option given below: All are correct
