Answer:
7. 2 ATP
8. People use NADH supplements as medicine. NADH is used for improving mental clarity, alertness, concentration, and memory; as well as for treating Alzheimer's disease and dementia. Because of its role in energy production, NADH is also used for improving athletic performance and treating chronic fatigue syndrome
9. Glycolysis involves the breaking down of a sugar into more manageable compounds in order to produce energy.
10. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen.
11. fermentation, carbon dioxide, is used in bread making and the production of carbonated beverages.
12. i dont know
13. The CO2 produced by the Krebs cycle is the same CO2 that you exhale. The electron carriers NADH and FADH are sent to the final step of cell respiration, which is respiratory electron transport. The Krebs cycle does not use oxygen, though it does stop in the absence of oxygen because it runs out of NAD and FAD.
14. Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
15. The Krebs cycle occurs in the mitochondrial matrix and generates a pool of chemical energy from the oxidation of pyruvate, the end product of glycolysis.
16. This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria.
17. In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.
