Example Questions

Example Question #2 : Calvin Cycle

What are the three stages of the Calvin cycle?

Possible Answers:

Reduction, oxidation, and regeneration

Fixation, carboxylation, and regeneration 

Fixation, reduction, and regeneration

Carboxylation, reduction, and regeneration

Fixation, oxidation, and regeneration

Correct answer:

Fixation, reduction, 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.

Example Question #3 : Calvin Cycle

Which of the following is not true of the Calvin cycle?

Possible Answers:

NADPH and ATP are required to initiate the Calvin cycle

The first step of the Calvin cycle is carbon fixation

The Calvin cycle occurs in the stroma of a chloroplast

All of these are true of the Calvin cycle

The Calvin cycle does not need light to function

Correct answer:

The Calvin cycle does not need light to function

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.
