What happens during the reduction stage of the Calvin cycle (light independent reactions)?

Question

A. The remaining G3P molecules that have not exited the cycle are used to reform RuBP through a series of chemical reactions so that the Calvin cycle can continue.
B. Energy from ATP and electrons from NADPH are used to reduce 3-phosphoglycerate to form G3P molecules (which can be used to form other organic molecules such as glucose)
C. Oxygen is produced through this process
D. Th enzyme rubisco attaches CO2 to RuBP causing the formation of molecules of 3-phosphoglycerate

Answer 1

The correct answer for what happens during the reduction stage of the Calvin cycle (light-independent reactions) is:

B. Energy from ATP and electrons from NADPH are used to reduce 3-phosphoglycerate to form G3P molecules (which can be used to form other organic molecules such as glucose).

During this stage, ATP and NADPH, which are generated during the light-dependent reactions of photosynthesis, are utilized to convert 3-phosphoglycerate (3-PGA) molecules into glyceraldehyde-3-phosphate (G3P). G3P is a three-carbon sugar that can be further processed to form glucose and other carbohydrates.
