Which process occurs in the stroma of the chloroplast?

• Electron transport chain

• Calvin cycle

• Light absorption

• ATP synthesis

How do ATP and NADPH produced in the light-dependent reactions contribute to the Calvin cycle?

• They provide oxygen for the cycle

• They supply energy and electrons for carbon fixation

• They break down glucose

• They absorb sunlight

Explain why the products of the light-dependent reactions are necessary for the Calvin cycle to proceed. Use evidence from the processes involved.

• The Calvin cycle requires ATP and NADPH to convert carbon dioxide into glucose.

• The Calvin cycle uses oxygen and water to produce ATP.

• The Calvin cycle only needs sunlight to function.

• The Calvin cycle produces ATP and NADPH for the light-dependent reactions.
