Final answer:
In the Calvin Benson cycle, ATP and NADPH provide energy and reducing power respectively. Carbon dioxide is fixed, glucose is produced, and the cycle takes place in the stroma of chloroplasts.
Step-by-step explanation:
The Calvin Benson cycle, also known as the Calvin cycle or C3 cycle, is a series of chemical reactions that takes place in the stroma of chloroplasts during photosynthesis.
ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate) play essential roles in the Calvin cycle. ATP provides the energy required for the synthesis of glucose, and NADPH provides the reducing power needed to convert carbon dioxide into carbohydrates.
Carbon dioxide (CO2) is the source of carbon atoms that are incorporated into glucose during the Calvin cycle. It enters the cycle during the fixation stage.
The stroma is the location where the Calvin cycle occurs. It is the fluid-filled space within the chloroplasts.
G3P (glyceraldehyde-3-phosphate) is an intermediate molecule produced during the reduction stage of the Calvin cycle. It can be used to synthesize glucose or regenerate RuBP (ribulose bisphosphate) to keep the cycle running.
The final product of the Calvin cycle is glucose (C6H12O6), a valuable source of energy for organisms.
