Question

Which of the following statements about the Calvin Cycle is CORRECT?

A. they only occur in the dark
B. they produce CO₂ and consume O₂
C. they convert CO₂ into organic compounds, such as glucose and starch

Answer 1

The Calvin Cycle converts CO₂ into organic compounds like glucose and starch, using energy from ATP and NADPH produced in the light-dependent reactions and can operate during both day and night. The correct option is C.

Step-by-step explanation:

The correct statement about the Calvin Cycle is that it converts CO₂ into organic compounds, such as glucose and starch. The Calvin Cycle, also known as the light-independent reactions of photosynthesis, utilizes the chemical energy stored in ATP and NADPH, which were produced in the light-dependent reactions.

Carbon fixation occurs when CO₂ is converted into organic compounds, and this cycle can take place during both day and night as it does not require light.

The Calvin Cycle is a crucial process for transforming inorganic carbon from the atmosphere into carbohydrates that living organisms can use for energy and growth.

This cycle involves the enzyme ribulose biphosphate carboxylase (RuBisCO) and results in the production of a three-carbon molecule called glyceraldehyde-3-phosphate (G3P), which is a precursor to glucose and other carbohydrates.
