Question

which explains how the calvin cycle and the krebs cycle differ?
the calvin cycle uses atp to make glucose.
the krebs cycle uses adp to make glucose.
only the calvin cycle occurs in plant cells.
the krebs cycle only repeats in animal cells.

Explanation:

• The Calvin cycle is part of photosynthesis. It uses ATP (produced in the light - dependent reactions) to fix carbon dioxide and make glucose.
• The Krebs cycle (citric acid cycle) is part of cellular respiration. It does not make glucose; it breaks down acetyl - CoA to produce ATP, NADH, and FADH₂. Both plants and animals have Krebs cycles (in mitochondria for aerobic respiration). Plant cells have both Calvin and Krebs cycles.

Answer:

The Calvin cycle uses ATP to make glucose.
