Verified step by step guidance
1
Understand that the Calvin cycle is a series of biochemical reactions that take place in the chloroplasts of photosynthetic organisms.
Recognize that the primary purpose of the Calvin cycle is to convert carbon dioxide and water into glucose, using the energy from ATP and NADPH produced in the light-dependent reactions of photosynthesis.
Identify the key process of the Calvin cycle: Carbon fixation, which involves the incorporation of carbon dioxide into organic molecules.
Note that glycolysis, beta-oxidation, and oxidative phosphorylation are not part of the Calvin cycle. Glycolysis is the breakdown of glucose, beta-oxidation is the breakdown of fatty acids, and oxidative phosphorylation is part of cellular respiration.
Conclude that carbon fixation is the correct process occurring during the Calvin cycle, as it is essential for synthesizing organic compounds from carbon dioxide.
