Question 7 • CMS 2026-2027 Biology CREDIT RECOVERY

How do ATP and NADPH connect light-dependent and light-independent reactions in photosynthesis?

Answer
A
ATP and NADPH are used in both reactions.
B
ATP and NADPH are produced in both reactions.
C
ATP and NADPH are produced in the light-independent reactions and used in the light-dependent reactions.
D
ATP and NADPH are produced in the light-dependent reactions and used in the light-independent reactions.

Explanation

The light-dependent reactions capture light energy and produce ATP and NADPH. The light-independent reactions, also called the Calvin cycle, use ATP for energy and NADPH to help reduce carbon dioxide into sugars. Therefore, ATP and NADPH are produced in the light-dependent reactions and used in the light-independent reactions, as choice C states.
