which process occurs during a light - independent reaction?
a a light source stimulates electrons to move through a chain of proteins called the electron transport chain
b the reaction uses the energy from atp and nadph molecules to form glucose from carbon dioxide.
c green chlorophyll molecules absorb solar energy
d atp and nadph molecules become energy carriers for the next stage of reactions

Explanation:

In light - independent reactions (Calvin cycle), energy from ATP and NADPH (produced in light - dependent reactions) is used to convert carbon dioxide into glucose. Option a and c are related to light - dependent reactions. Option d is a general statement about ATP and NADPH but not the main process of light - independent reactions. Option b correctly describes the process where the energy from ATP and NADPH is used to form glucose from carbon dioxide.

Answer:

B. The reaction uses the energy from ATP and NADPH molecules to form glucose from carbon dioxide.
