Biology CLEP Prep Practice Exam

What is the Calvin cycle?

1. A series of reactions in which carbon dioxide and light energy are used to produce sugar molecules

2. A mechanism by which enzymes are destroyed

3. The technique of using enzymes to create genetic variation

4. A system of cells for regulating fluid levels in the body

The correct answer is: A series of reactions in which carbon dioxide and light energy are used to produce sugar molecules

The Calvin cycle is a biochemical process that takes place in the chloroplasts of plant cells. It involves a series of reactions in which carbon dioxide and light energy are used to produce sugar molecules, which the plant then uses for energy. Option B is incorrect because the Calvin cycle does not involve enzyme destruction. Option C is incorrect because the Calvin cycle does not involve enzymes creating genetic variation. Option D is incorrect because the Calvin cycle is not related to regulating fluid levels in the body.
