Explanation / Answer

Q34. The Calvin cycle uses 18 ATP and 12 NADPH molecules to produce one glucose molecule. thus for the production of sucrose total 24 x 4 = 96 photons are required

35.in stroma of chloroplast

36. c all cells have rubisco activity

37. in c3 plants carbon fixation takes place in mesiohyl cells

38.c photorespiration require three orgnelles

39.e hatch slack cycle

40. e hatch slack cycle
