1. TRUE or FALSE: The glycolysis pathway isreversible to allow glucose production from specific deaminatedamino acids during fasting.

1. True
2. False

1. What happens to the amino group of deaminatedamino acids?

1. The liver can metabolize it to glucose by gluconeogenesis.
2. The liver metabolize it to urea
3. The liver metabolize it to ketones

1. What will happen to the carbon skeleton of thedeaminated amino acids when excessive protein and calories areconsumed?

a. It is metabolized by the liver to urea

b. They will be metabolized to fat

c. They will be metabolized to ketones

1. What is the main function of the coenzymes NAD+ and FAD?

1. To form water
2. To act as enzymes by removing hydrogen atoms fromsubstrate
3. To transport hydrogen atoms to the electron transportchain.

1. During the oxidation of glucose, what happens to the carbons asthey are removed from glucose?

1. They produce water
2. They bond to NAD+
3. They form CO2
4. They form Coenzyme A

1. What happens during the Kreb Cycle?.

1. 3 molecules of NAD⁺ and one molecule of FAD arereduced per cycle
2. 1 ATP is produced at the substrate level per cycle
3. Carbon is removed from substrates of the Kreb Cycle as Carbondioxide and expired by the lungs.
4. All of the above

1.   Which of the following isFALSE?

1. Members of the electron transport chain are activated byelectrons, turning them into proton pumps.
2. Protons and ATP are transported out of the mitochondria andinto the cytoplasm by a proton-ATP exchanger
3. The diffusion of protons through Respiratory Assembliesactivates ATP synthase .
4. The splitting of ATP activates members of the electrontransport chain, turning them into pumps.

1. During the oxidation of glucose, the greatest amount of ATP isproduced:

1. At the substrate level
2. By oxidative phosphorylation (Electron Transport Chain)
