Q

What is Carbon Fixation?

A

When three carbon dioxide attach (each) to one organic molecule that contains 5 CO2 which is Ribulose bisphosphate with an enzyme called Rubisco.

Q

What happens in the last step Recycle?

A

Basically 1 G3P is needed for net gain to make glucose and 5 G3P to regenerate W/ATP to create Ribulose Bis phosphate. Also, you need two G3P molecules to make glucose so you need the cycle to go twice to make glucose.
