Multiple Choice
Which of the following statements is true about the Calvin cycle in organic chemistry reactions?
A
The Calvin cycle is a series of light-dependent reactions that occur in the thylakoid membranes.
B
The Calvin cycle occurs in the mitochondria of plant cells.
C
The Calvin cycle is a light-independent process that synthesizes glucose from carbon dioxide and water.
D
The Calvin cycle directly produces ATP and NADPH as its main products.
Verified step by step guidance
1
Understand that the Calvin cycle is part of photosynthesis, which occurs in plants, algae, and some bacteria.
Recognize that the Calvin cycle is a light-independent reaction, meaning it does not require light to proceed, unlike the light-dependent reactions.
Identify the location of the Calvin cycle: it takes place in the stroma of chloroplasts, not in the thylakoid membranes or mitochondria.
Clarify the main purpose of the Calvin cycle: it synthesizes glucose from carbon dioxide and water using ATP and NADPH produced in the light-dependent reactions.
Note that the Calvin cycle does not directly produce ATP and NADPH; instead, it uses these molecules to drive the synthesis of glucose.
