Questions & Step-by-Step Solutions

Which enzyme is crucial for carbon fixation in the Calvin cycle?
Correct Answer: Rubisco
  • Step 1: Understand what carbon fixation is. It is the process of converting carbon dioxide (CO2) into organic compounds.
  • Step 2: Learn about the Calvin cycle. It is a series of biochemical reactions that occur in plants during photosynthesis.
  • Step 3: Identify the enzyme involved in the first step of the Calvin cycle. This enzyme is responsible for helping to fix carbon dioxide.
  • Step 4: Recognize that the enzyme is called Rubisco, which stands for ribulose bisphosphate carboxylase/oxygenase.
  • Step 5: Conclude that Rubisco is crucial for carbon fixation in the Calvin cycle.
