Question

question 34
which of the following characterize the calvin cycle?
a nitrogen is fixed into an organic form
b produces glucose as an end product
c produces oxygen
d a process that requires light
e produces carbon dioxide and water

Explanation:

The Calvin cycle is part of photosynthesis. It uses ATP and NADPH (from the light - dependent reactions) to fix carbon dioxide (\(CO_2\)) and produce glucose.

• Option A: Nitrogen fixation is a different process (not part of the Calvin cycle).
• Option C: Oxygen is produced in the light - dependent reactions of photosynthesis, not in the Calvin cycle.
• Option D: The Calvin cycle is a light - independent (dark) reaction.
• Option E: Carbon dioxide is consumed (not produced) in the Calvin cycle, and water is not a product of the Calvin cycle.

Answer:

B. Produces glucose as an end product
