Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>
The Calvin cycle proceeds in three stages:
1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate
2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH
3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.
group 3, because biotic factors are only living things
