Carbon dioxide fixation can be enhanced by enhancing the efficiency of:
Correct answer: B. Ribulose bisphosphate
- A. Auxins
- B. Ribulose bisphosphate
- C. Lactoferrin
- D. Agrobacterium
Explanation
Carbon dioxide fixation, particularly in the context of photosynthesis, can be enhanced by enhancing the efficiency of the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO). RuBisCO is a key enzyme involved in the first step of the Calvin Cycle, where carbon dioxide is fixed into organic molecules.

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.
