Question

Quizplus · Accepted Answer

Six rounds of the Calvin cycle are required for the production of one molecule of glucose (a hexose). This is because the Calvin cycle starts with six molecules of CO2, which are fixed and reduced to form six molecules of glyceraldehyde 3-phosphate (G3P). Two of these G3P molecules can then be combined to form glucose. Therefore, six rounds of the Calvin cycle are necessary to produce one glucose molecule, which is a hexose.
