______________________
__ | NAD+ an FAD become reduced. |
__ | High-energy carbon dioxide molecules will be generated by substrate-level phosphorylation. |
__ | ATP is synthesized by chemiosmosis. |
__ | The organic carbon (from acetyl CoA) that enters the cycle will be completely oxidized in the mitochondrial matrix. |
__ | Citrate must be continuously regenerated to prepare the cycle to process incoming acetyl CoA. |
__ | Upon entry into the citric acid cycle, acetyl CoA is combined with oxaloacetate. |
__ | Two ATP molecules will be consumed for each acetyl CoA that is processed by the cycle. |
__ | Organic molecules are oxidized in several different steps of the cycle. |

Question 48
Soccer (assuming field player) is a sport which is 90% aerobic.
True
False
Question 50
Glucose is necessary for fatty acid oxidation because...
its derivative, pyruvate, is condensated with carbonic acid to form oxaloacetate, which in turn is a necessary carbon compound in the citric acid cycle | ||
it is needed to convert fatty acids to fatty acyl-CoA which in turn is oxidized to acetyl CoA | ||
glucose is decarboxylated into cytochrome oxidase which is a necessary intermediate in the citric acid cycle | ||
its derivative, acetyl CoA, is condensated with carbonic acid to form lactase, which in turn is a necessary carbon compound in the citric acid cycle |
Question 51
In aerobic ATP production, the role of oxygen is to...
to keep the electron transport chain operational | ||
to accept electrons from the 3rd cytochrome and thereby oxidizing it so it can accept new electrons | ||
act as a oxidizing agent by accepting electrons from the electron transport chain and combining with hydrogen ions (protons) | ||
all of the above |
Question 52
The primary purpose of the citric acid cycle is...
aerobic glycolysis | ||||||||||||||
gluconeogenesis using lactate | ||||||||||||||
