Which of the following is not produced in the light-dependent reactions of photosynthesis? A. NADPH B. sugars C. ATP D. oxygen User: In the process of aerobic respiration, the Krebs Cycle (Citric Acid Cycle) occurs in the A. chloroplasts. B. nuclei. C. lysosomes. D. mitochondria.
Weegy: This is also called the Krebs cycle or the tricarboxylic acid cycle. When oxygen is present, acetyl-CoA is produced from the pyruvate molecules created from glycolysis. [ Once acetyl-CoA is formed, two processes can occur, aerobic or anaerobic respiration. When oxygen is present, the mitochondria will undergo aerobic respiration which leads to the Krebs cycle. However, if oxygen is not present, fermentation of the pyruvate molecule will occur. In the presence of oxygen, when acetyl-CoA is produced, the molecule then enters the citric acid cycle (Krebs cycle) inside the mitochondrial matrix, and gets oxidized to CO2 while at the same time reducing NAD to NADH. NADH can be used by the electron transport chain to create further ATP as part of oxidative phosphorylation. To fully oxidize the equivalent of one glucose molecule, two acetyl-CoA must be metabolized by the Krebs cycle. Two waste products, H2O and CO2, are created during this cycle. citric acid ] User: The light-independent reactions of photosynthesis are also known as the A. Calvin cycle. B. Priestly cycle. C. Benson cycle. D. van Helmont cycle. Weegy: The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes. [ These reactions take the light-dependent reactions and perform further chemical processes on them. There are three phases to the light-independent reactions, collectively called the Calvin cycle ] User: which one? a b c d Weegy: hi the answer is A. thank you for your question (More)
