Question

Photosynthesis can be divided into two steps: the light-dependent reactions and the Calvi cycle. Which of the following correctly describes the overall process of the Calvin cycle?

A) The Calvin cycle occurs in the thylakoid membrane of chloroplasts
B) During the Calvin cycle, carbon is oxidized.
C) ATP and NADPH produced by the light reactions are used by the Calvin cycle to make carbohydrates
D) The Calvin cycle breaks down carbohydrates into simpler molecules

Answer 1

C) ATP and NADPH produced by the light reactions are used by the Calvin cycle to make carbohydrates

Step-by-step explanation:

The light-dependent reactions of photosynthesis form ATP and NADPH. These reactions occur in the thylakoid membrane of chloroplasts.

The light-independent reactions of photosynthesis, the Calvin cycle occurs in the stroma of chloroplast as the enzymes for the reactions of the Calvin cycle are present in the stroma.

During the Calvin cycle, the atmospheric carbon dioxide is fixed into glucose using the ATP as an energy source and NADPH as the electron donor for redox reactions.
