Question

in one to three sentences, describe what happens during the carbon fixation stage of the calvin cycle.

Explanation:

Carbon fixation in the Calvin cycle involves the enzyme RuBisCO catalyzing the reaction of CO₂ with RuBP (ribulose - 1,5 - bisphosphate) to form an unstable six - carbon compound. This compound quickly splits into two molecules of 3 - phosphoglycerate (3 - PGA).

Answer:

Carbon fixation in the Calvin cycle is the process where CO₂ is combined with RuBP (ribulose - 1,5 - bisphosphate) by the enzyme RuBisCO. The initial product is an unstable six - carbon molecule that breaks down into two molecules of 3 - phosphoglycerate (3 - PGA).
