Biochemistry › Other Calvin Cycle Concepts
Which of the following is not true of the Calvin cycle?
The Calvin cycle does not need light to function
The Calvin cycle occurs in the stroma of a chloroplast
The first step of the Calvin cycle is carbon fixation
NADPH and ATP are required to initiate the Calvin cycle
All of these are true of the Calvin cycle
Explanation
Despite the Calvin cycle's other name (light independent reactions), light is indirectly required for this process to function. All other choices are true of the Calvin cycle.
What are the three stages of the Calvin cycle?
Fixation, reduction, and regeneration
Fixation, oxidation, and regeneration
Carboxylation, reduction, and regeneration
Reduction, oxidation, and regeneration
Fixation, carboxylation, and regeneration
Explanation
The stages of the Calvin cycle in the order that they occur are fixation, reduction, and then regeneration. While carboxylation does occur as a part of the first stage, it is not what defines that stage.
