Question

during the second set of photosynthetic reactions, called the calvin cycle, all but one of the following occurs. a glucose is the end product of the calvin cycle. b by - products of the calvin cycle include water vapor and oxygen. c carbon dioxide, a reactant of photosynthesis, is utilized during the calvin cycle. d atp and nadph, high energy molecules, are utilized to produce stored chemical energy.

Explanation:

In the Calvin - cycle, glucose is produced from carbon dioxide using ATP and NADPH. Oxygen is a by - product of the light - dependent reactions, not the Calvin cycle. Water vapor is not a by - product of the Calvin cycle. Carbon dioxide is used as a reactant in the Calvin cycle and ATP and NADPH are used to drive the reactions to produce stored chemical energy in the form of glucose.

Answer:

B. By - products of the Calvin cycle include water vapor and oxygen.
