Question

Explain what happens during the carbon fixation phase of the Calvin Cycle. Your answer should definitely include the name of the enzyme that catalyzes the first step, the reactants in the first step,

Answer 1

During the carbon fixation phase of the Calvin Cycle, carbon dioxide is converted into an organic molecule using an enzyme called RuBisCO.

Step-by-step explanation:

The carbon fixation phase of the Calvin Cycle is where carbon dioxide (CO2) is converted into an organic molecule. The enzyme responsible for this conversion is called ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO).

In the first step of carbon fixation, RuBisCO combines CO2 with a five-carbon molecule called ribulose bisphosphate (RuBP) to form a six-carbon compound. This compound is then broken down into two three-carbon compounds, which continue through the reduction and regeneration stages of the Calvin Cycle.
