Question

Choose the correct answer from the alternatives given.
Which of the following is most closely associated with the Calvin cycle?

• A. ATP production
• B. Oxygen production
• C. Carbon dioxide fixation
• D. Carbon dioxide production

Answer 1

Answer: (C)

Carbon dioxide fixation

Calvin cycle is composed of a series of enzymes that utilize the energy conserved in the light-dependent reaction to reduce atmospheric CO2 to glucose. The cycle starts with a 5C ribulose bisphosphate (RuBP) molecule being complexed with the CO2 by an enzyme Ribulose 1,5 bis-phosphate carboxylase (Rubisco), later recycled and the process results in the formation of glucose.

So, the correct answer is 'Carbon dioxide fixation'.
