Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following are products of the light reactions of photosynthesis that are utilised in the Calvin cycle?
A
Electrons and H+
B
CO2 and glucose
C
ATP and NADPH
D
ADP, Pi and NADPH
Explanation: 

Detailed explanation-1: -The light reaction of photosynthesis produces ATP and NADPH which in turn serve as the energy source to drive the second phase of photosynthesis (dark reactions) during which carbohydrate synthesis takes place.

Detailed explanation-2: -This illustration shows that ATP and NADPH produced in the light reactions are used in the Calvin cycle to make sugar.

Detailed explanation-3: -ATP and NADPH formed during light reaction of photosynthesis are used in dark reaction for fixing CO2 and to form glucose molecule.

Detailed explanation-4: -The Calvin cycle is part of the light-independent reactions of photosynthesis. The Calvin cycle uses ATP and NADPH.

Detailed explanation-5: -NADPH formation. The net effect of these steps is to convert light energy into chemical energy in the form of ATP and NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.
