Final answer:
The Calvin Cycle converts CO2 into Glyceraldehyde-3-phosphate (G3P), which is ultimately used to form glucose and other carbohydrates using energy from ATP and NADPH.
Step-by-step explanation:
During the Calvin Cycle of photosynthesis, stored energy is used to convert CO2 into a three-carbon molecule called Glyceraldehyde-3-phosphate (G3P), which is then converted into glucose and other carbohydrates. The Calvin Cycle uses the energy from ATP and NADPH, produced by the light-dependent reactions, to fix carbon from CO2 into organic compounds.
After three turns of the cycle, one G3P molecule exits the cycle to be used in forming carbohydrates, while the remaining G3P molecules are recycled to regenerate the initial acceptor molecule, ribulose biphosphate (RuBP), ensuring the cycle can continue.
