16
Q

Stage one: Carbon Fixation

A

the enzyme RuBisCO fixes or attached carbon dioxide into a 5 carbon organic molecule

17
Q

Stage 2: Reduction

A

ATP and NADPH reduce the newly formed compound by transferring electrons and sugar is made and leaves the cycle

18
Q

Stage 3: Regeneration

A

RuBP is regenerated so the cycle can continue

19
Q

Summary of Calvin Cycle

A

It takes 6 turns of the Calvin Cycle to fix 6 carbon atoms from 6CO2. These 6 turns require energy input from 9 ATP molecules and 6 NADPH molecules. The result is 1 glucose molecule.
