Question

Which of the following happens to the molecule formed by the addition of carbon dioxide to ribulose bisphosphate?

O It is immediately split into two more stable three-carbon molecules.
O It is immediately stored within the chloroplast for conditions exclusive of photosynthesis.
It is the starting point for cellular respiration.
O It is used to reduce three molecules of NADPH.

Answer 1

When carbon dioxide is added to ribulose bisphosphate, it is split into two more stable three-carbon molecules called phosphoglycerate.

Step-by-step explanation:

When carbon dioxide is added to ribulose bisphosphate, the resulting molecule undergoes a process called carbon fixation. It is immediately split into two more stable three-carbon molecules called phosphoglycerate. This process occurs during the light-independent reactions of photosynthesis, specifically in a cycle called the Calvin cycle.
