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

For each ATP produced, what is the number of ${\mathrm{H}}^{+}$ that passes through F0 from the intermembrane space to the matrix down the electrochemical proton gradient?
1. 1
2. 2
3. 3
4. 4

According to NCERT textbook, what is the number of ATP molecules that can be regarded as a net gain during aerobic respiration of one molecule of glucose?

What is the number of ATP molecules produced when pyruvate is converted to lactate by fermentation?

If fatty acids were to enter the respiratory pathway, they must be converted to a molecule with:

The respiratory pathway is best described as:

The correct descending order of the RQ value, when carbohydrates, proteins and fats are used as respiratory substrate would be:
1. Protein ˃ Fats ˃ Carbohydrates
2. Protein ˃ Carbohydrates ˃ Fats
3. Carbohydrates ˃ Protein ˃ Fats
4. Fats ˃ Carbohydrates ˃ Protein
