The light-independent reactions, also known as the Calvin cycle, are primarily used for

A.D) Releasing O2 as a byproduct of photosynthesis.

B.A) Producing ATP and NADPH from light energy.

C.B) Fixing CO2 into glucose and other organic compounds.

D.C) Regenerating NAD+ and ATP from NADH and ADP.

Explanation

Core Concept

The Calvin cycle is primarily used for fixing CO2 into glucose and other organic compounds, using the ATP and NADPH produced in the light-dependent reactions to drive this process. This is a key step in photosynthesis, allowing plants to convert CO2 into organic compounds necessary for growth and development. Options A, C, and D are incorrect because the light-independent reactions do not produce ATP and NADPH, regenerate NAD+ and ATP, or release O2.
