Question

What is the equation for the Calvin cycle?

Answer 1

There is no equation for calvin cycle alone as it part of a bigger process which can be represented by an equation.

Explanation:

The photosynthesis process has reactants and products like any other reaction.
The light dependent reaction uses water and gives oxygen, while the independent one uses carbon dioxide an gives glucose.
Both stages are represented by the known equation for photosynthesis:
water + carbon dioxide = oxygen + glucose
