4short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is dependence on the light stage?Show answer
The cycle cannot run without the ATP and reduced NADP from the light-dependent reactions. This is why, although the Calvin cycle does not directly use light, it stops soon after the light is removed.
What is q1?Show answer
State where in the chloroplast the Calvin cycle occurs. [1 mark]
What is q2?Show answer
Name the enzyme that catalyses the fixation of carbon dioxide and the molecule it acts on. [2 marks]
