Question

"The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which: decreases cell carbon dioxide levels, which increases the diffusion gradient.

A True
B False"

Answer 1

The first event in the Calvin cycle is the attachment of carbon dioxide to the five-carbon RuBP molecule, which results in the formation of a six-carbon molecule.

Step-by-step explanation:

True.

In the Calvin cycle, the first event is the attachment of carbon dioxide to the five-carbon RuBP molecule. This process is catalyzed by the enzyme RuBisCO, resulting in the formation of a six-carbon molecule. However, the six-carbon molecule is quickly split into two three-carbon molecules. These three-carbon molecules are then used in subsequent reactions to produce glucose.
