The Calvin cycle, also known as the light-independent or "dark" reactions, is the second stage of photosynthesis. It takes place in the stroma of the chloroplast and converts carbon dioxide and other compounds into glucose. The cycle involves three stages:

1. Carbon Fixation: The enzyme RuBisCO catalyses the fixation of atmospheric CO2 into a 5-carbon sugar called ribulose bisphosphate. This results in a 6-carbon compound that immediately splits into two molecules of 3-phosphoglycerate.

2. Reduction: ATP and NADPH from the light-dependent reactions are used to convert 3-phosphoglycerate into glyceraldehyde 3-phosphate (G3P). This is a 3-carbon sugar which can be used to form glucose.

3. Regeneration: Some G3P molecules are used to regenerate ribulose bisphosphate so the cycle can continue.

So, the Calvin cycle involves the presence of carbon dioxide, ATP, NADPH, and the enzyme RuBisCO.
