What molecule adds phosphates to the intermediates in the Calvin cycle?
|
NADPH
|
|
NADP+
|
|
ATP
|
|
ADP
|
Explanation:
Detailed explanation-1: -Figure 1 The light-dependent reactions harness energy from the sun to produce ATP and NADPH. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place.
Detailed explanation-2: -The intermediates of the Calvin Cycle include ADP, NADP+, inorganic phosphate, and 3-phosphoglycerate.
Detailed explanation-3: -Overview of the Calvin cycle This process is fueled by, and dependent on, ATP and NADPH from the light reactions.
Detailed explanation-4: -Six molecules of both ATP and NADPH are used. For ATP, energy is released with the loss of the terminal phosphate atom, converting it to ADP; for NADPH, both energy and a hydrogen atom are lost, converting it into NADP+.
