(B) The products of light reaction are ATP, NADPH and O₂.
(C) The acceptor molecule of CO₂in dark reaction is a 5-C aldehyde sugar – RuBP
(D) The fixations of 6 molecules of CO₂ and 6 turns of the cycle are required for the removal of one molecule of glucose from the calvin cycle pathway.
(E) For every CO₂ molecule entering the calvin cycle, 2 molecules of ATP and 2 of NADPH are required.
(F) C₄ plants have a special type of leaf anatomy, tolerate higher temperatures and lack process of photorespiration and have greater productivity of biomass.
(G) Small cells around the vascular bundles of the C₄ pathway plants are called bundles 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) C₄ pathway has been named Hatch and Slack pathway.
(J) In C₄ plants, the primary CO₂ acceptor is a 3-C molecule PEP and is present in the bundle sheath cells.
