Fixation phase of calvin cycle
WebQuestion 14 1 Point During the carbon fixation phase of the Calvin Cycle, carbon dioxide is incorporated into ribulose bisphosphate, a five carbon sugar. This reaction specifically produces a six-carbon intermediate that immediately splits in half to form 3-phosphoglycerate molecules. WebJan 17, 2024 · As Melvin Calvin discovered, carbon fixation is the first step of a cycle. Like an electron transport chain, the Calvin cycle, shown in Figure below, transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron t ransport chain, excited electrons lose energy to NADPH and ATP.
