Which of the following is NOT true about light-independent photosynthesis? a. Light-independent reactions take the products of t
he 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.
1 answer:
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.
