Final answer:
The Calvin Cycle, or dark reactions, produce glucose as its final product using ATP and NADPH from the light-dependent reactions to convert CO2 into carbohydrates.
Step-by-step explanation:
The products of the dark reactions (also known as the Calvin Cycle or light-independent reactions) are organic compounds like glucose. These reactions do not require light and take place in the stroma of the chloroplasts. The cycle uses ATP and NADPH generated by the light-dependent reactions to convert carbon dioxide from the atmosphere into carbohydrates.
The cycle can be divided into three stages: fixation, reduction, and regeneration. In the fixation stage, carbon dioxide is attached to RuBP (ribulose-1,5-bisphosphate) by the enzyme RuBisCO. The reduction stage utilizes ATP and NADPH to reduce 3-phosphoglycerate into glyceraldehyde-3-phosphate (G3P), which can then be used to synthesize glucose. Lastly, the regeneration stage remakes RuBP, enabling the cycle to continue.
