Answer:
The correct answer is B) "there is a close relationship between carbohydrate synthesis and carbohydrate metabolism".
Explanation:
The Calvin cycle are a series of chemical reactions that occurs in plant's stroma, and allow the convert carbon dioxide and other compounds into glucose in the absence of light. Most of the enzymes that function in Calvin cycle function as well in metabolic pathways, because there is a close relationship between carbohydrate synthesis and carbohydrate metabolism. Particularly, gluconeogenesis and the pentose phosphate pathway have equivalent enzymes that those found in the Calvin cycle.
