Question

how do atp and nadph connect light - dependent and light - independent reactions in photosynthesis?
atp and nadph are produced in both reactions.
atp and nadph are used in both reactions.
atp and nadph are produced in the light - dependent reactions and used in the light - independent reactions.
atp and nadph are produced in the light - dependent reactions and used in the light - dependent reactions.
atp and nadph are produced in the light - independent reactions and used in the light - dependent reactions.

Explanation:

In photosynthesis, light - dependent reactions convert light energy into chemical energy in the form of ATP and NADPH. These energy - rich molecules are then used in the light - independent reactions (Calvin cycle) to fix carbon dioxide and produce glucose.

Answer:

ATP and NADPH are produced in the light - dependent reactions and used in the light - independent reactions.
