Final answer:
The Calvin cycle is also known as C3 photosynthesis due to the three-carbon intermediate it produces and involves three stages: fixation, reduction, and regeneration.
Step-by-step explanation:
The Calvin cycle is also known as C3 photosynthesis because the first intermediate of the cycle contains three carbon atoms. The Calvin cycle occurs in the stroma of chloroplasts where it uses carbon dioxide (CO2) and the energy from ATP and NADPH to produce glucose. This series of reactions can be divided into three stages: fixation, where CO2 is attached to a five-carbon sugar called ribulose bisphosphate (RuBP); reduction, where energy and electrons are transferred to the fixed carbon to form a three-carbon sugar; and regeneration of RuBP, which allows the cycle to continue. The Calvin cycle is essential for photosynthesis in plants and photoautotrophic bacteria and involves the enzyme Ribulose-1,5-bisphosphate carboxylase/oxygenase, commonly known as RuBisCO, which is one of the most abundant enzymes on earth.
The Calvin cycle is also known as the light-independent photosynthesis because the first intermediate of the cycle contains three carbon atoms. The Calvin cycle is a series of chemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is converted into glucose. It consists of three stages: fixation, reduction, and regeneration.
