Which of the following is not true about light-independent photosynthesis? a. light-independent reactions take the products of the light-dependent reactions and convert them to carbohydrates and oxygen. b. the calvin-benson cycle is terminated when rubisco acquires a carbon from the atmosphere in the form of carbon dioxide. c. the calvin-benson cycle is initiated when the enzyme rubisco acquires carbon from the atmosphere in the form of carbon dioxide. d. the calvin-benson cycle is composed of multiple reactions that link carbon atoms to form simple sugars.

B

Rather, the Calvin-Benson Cycle is BEGINS when RuBP acquires a carbon from the atmosphere in the form of carbon dioxide to become RuBisCO.

Explanation:

Calvin cycle is the dark phase cycle in plants that generates carbohydrates from reduction of carbon dioxide. The products of light phase – ATPs and NADPH -  are used in the Calvin cycle which is a catabolic pathway.

Calvin cycle BEGINS with a RuBP (Ribulose 1,5-bisphosphate) molecule that captures 3 carbon dioxide molecules to become a Rubisco. The Rubisco is hydrolysed into six 3-PGA which are reduced to G3Ps. One G3P is used to make glucose while the others are used to regenerate RuBP.
