How many ATP molecules are directly synthesized in glycolytic pathway from one glucose molecule?

1. 2	2. 4
3. 6	4. 10

What is the metabolic fate of pyruvate?
1. It is the end product of glycolytic pathway
2. It is reduced to acetyl CoA in the presence of oxygen
3. It depends on the cellular needs
4. It is decarboxylated in the cytosol

The maximum concentration of alcohol in beverages that are naturally fermented is about:

The continued oxidation of acetyl CoA via the TCA cycle requires the continued replenishment of:

At how many points in the TCA cycle is ${\mathrm{NAD}}^{+}$ reduced to NADH + ${\mathrm{H}}^{+}$?

During the conversion of succinyl CoA to succinic acid in TCA cycle:
1. One molecule of ATP is directly synthesized
2. ${\mathrm{NAD}}^{+}$ is reduced
3. FAD is reduced
4. One molecule of GTP is synthesized

The electron transport system in mitochondria is located in the:
1. Inner mitochondrial membrane
2. Outer mitochondrial membrane
3. Inter membrane space
4. Matrix

Cytochrome c is found:

The number of ATP molecules synthesized from oxidation of one molecule of NADH and one molecule of ${\mathrm{FADH}}_2$ are respectively:

Oxygen drives the process of ATP production via ETS. The best explanation for this would be that oxygen:
1. is needed at the end of the aerobic respiration
2. is the terminal electron donor
3. is not required in the glycolytic pathway
4. acts as the final hydrogen acceptor
