Question

what happens to carbon dioxide molecules in the light independent reactions

Answer 1

In the Calvin Cycle?
A 6 carbon molecule enters the cycle and joins with 6 five carbon molecules. These then become 12 three carbon molecules.

These carbon molecules are then turned into higher forms of energy. The energy for this conversion comes from ATP and high-energy electrons from NADPH.

2 of the twelve 3 carbon molecules are removed from the cycle. The plant cell uses these molecules to produce sugars, lipids, amino acids, and other compounds needed for plant metabolism and growth.

The remaining 10 three carbon molecules are converted back into 6 five carbon molecules to begin the next cycle.

This is a steady process of removing carbon dioxide in the Calvin Cycle of Photosynthesis.
