Initial incorporation of carbon dioxide into organic material refers to which reaction?
Correct answer: B. Carbon fixation
- A. Calvin cycle
- B. Carbon fixation
- C. Reduction phase of calvin cycle
- D. Regeneration of RUBP
Explanation
A. In this reaction, carbon is fixed and reduced resulting in the synthesis of sugars during dark reactionsC. PGA receives an additional phosphate from ATP of light reaction forming 1,3- bisphosphoglycerate and this product reduces to G3PD. five molecules of G3P are used to generate 3 molecules of five carbon RuBP.

The more specific you are, the faster it gets fixed. A source beats an opinion.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
