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

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 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

Phosphorylation of glucose during glycolysis is catalysed by

Pyruvic acid, the key product of glycolysis can have many metabolic fates. Under aerobic condition, it forms

What is the end product of glycolysis?

The outputs of the Krebs cycle do not include:

The products of fermentation do not include:
