Question

The energy required to run the Calvin cycle reactions of photosynthesis comes from which two substances produced during the light-dependent reactions?

a. ATP and NADPH
b. ADP and PO₄
c. H⁺ and O₂
d. O₂ and CO₂
e. H₂O and CO₂

Answer 1

The Calvin cycle requires ATP and NADPH produced during the light-dependent reactions of photosynthesis to synthesize glucose from carbon dioxide.

Step-by-step explanation:

The energy required to run the Calvin cycle reactions of photosynthesis comes from two substances produced during the light-dependent reactions: ATP and NADPH.

These molecules are crucial for the light-independent reactions, as ATP provides the energy, and NADPH provides the reducing power necessary to convert carbon dioxide into glucose. Both ATP and NADPH are synthesized in the light-dependent reactions where light energy is transformed into chemical energy.
