WebThe cycle of oxygen isthe distribution of oxygen through nature in different ways. Free in the air and dissolved in water, in excess of uncombined elements in the atmosphere, oxygen is second only to nitrogen. In order … WebThe Calvin cycle is part of photosynthesis, which occurs in two stages. In the first stage, chemical reactions use energy from light to produce ATP and NADPH.

Photosynthesis - The process of photosynthesis: carbon fixation …
WebThe Calvin cycle takes the products of the light reactions and uses them to form O 2 and sugar. Photosynthesis can thus be summarized as: 6 C O 2 + 6 H 2 O + Light Energy → C 6 H 12 O 6 + 6 O 2 Image Credit: CK-12 Foundation, CC-BY-NC-SA 3.0 Key Terms Autotroph: Organisms that produce their own organic compounds (food). Web3) The addition of oxygen to RuBP shuts down the light-capturing reactions of photosynthesis, so the ATP and NADPH that drive the Calvin cycle reactions are not produced. 4) Photorespiration metabolizes the glucose that is synthesized during the Calvin cycle reactions, so it increases the net quantity of the products of the Calvin cycle. WebMolecular oxygen is produced during _____. A noncyclic electron flow during the light reactions 9 Q The reactions of the Calvin cycle are not directly dependent on light, but they usually do not occur at night. Why? A The Calvin cycle requires products only produced when the photosystems are illuminated. 10 Q The Calvin cycle occurs in the _____. A diskopum jember
