Question

Where does the Calvin cycle occur and does it need light

Answers

GPT-4o mini
The Calvin cycle occurs in the stroma of chloroplasts in plant cells. It is part of the process of photosynthesis and specifically takes place after the light-dependent reactions, which occur in the thylakoid membranes of the chloroplasts.

The Calvin cycle does not directly require light; instead, it uses the ATP and NADPH generated during the light-dependent reactions, which are light-dependent processes. However, since these reactions typically occur during the day when there is light, the Calvin cycle is often referred to as the "light-independent reactions." Despite this terminology, the Calvin cycle is usually active when there is light because it relies on the products of the light-dependent reactions.

The Calvin cycle occurs in the stroma of chloroplasts and does not directly require light, but it depends on energy carried by ATP and NADPH produced during the light-dependent reactions.
