The reaction of carbon dioxide and RUBP is catalyzed by?
Correct answer: C. Rubisco
- A. ATP synthase
- B. Globulin
- C. Rubisco
- D. NADH dehydrogenase
Explanation
The reaction between carbon dioxide (CO2) and ribulose-1,5-bisphosphate (RuBP) is catalyzed by the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known as Rubisco. This reaction is a crucial step in the Calvin cycle, which is the light-independent phase of photosynthesis responsible for the fixation of carbon dioxide and the synthesis of carbohydrates. Rubisco adds carbon dioxide to RuBP, leading to the formation of an unstable six-carbon compound that immediately splits into two molecules of 3-phosphoglycerate (3-PGA).

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.
