high-energy sugar
O carbon dioxide gas

The product of Calvin's cycle is high energy sugar.

Explanation:

The Calvin cycle involves a group of chemical reactions in which glucose is obtained from carbon dioxide (CO₂). These reactions occur in the dark phase of photosynthesis and consume energy, to produce a high energy sugar.

The first phase of Calvin's cycle involves the assimilation of CO₂, which he does by binding the gas to ribulose bisphosphate. The second phase consists of glucose synthesis through a specific sequence of steps where NADPH and ATP provide the energy needed for this process.
