Takes place in the stroma of chloroplasts
ATP and reduced NADP supply energy and hydrogen to make glucose from CO2
CO2 enters leaf and diffuses into stroma of chloroplast where it combines with RuBP (Rubisco)
Breaks down into two GP molecules where ATP from LDR, H+ ions from rNADP reduce the GP into GALP
rNADP is recycled back to NADP
GALP is converted into glucose, proteins, lipids, carbohydrates, nucleic acids, amino acids
5 of 6 GALP are used to regenerate RuBP
6 turns of cycle make a glucose molecule as glucose required 6 carbon molecules
Therefore it requires 18 ATP and 12 rNADP molecules
