Enumerate the assumptions that we undertake in making the respiratory balance sheet. Are these assumptions valid for a living system? Compare fermentation and aerobic respiration in this context.

 

 

Answers (1)

The assumptions that are made during the calculation of a respiratory balance sheet are:

- An orderly and sequential pathway is followed in the process of respiration.
- During the process of glycolysis, NADH is produced. This undergoes oxidative phosphorylation inside the mitochondria.
- No intermediate products are utilised in the formation of other products
- Glucose is oxidised only, and no other substance is utilised at any in-between stages The above assumptions are invalid for a living organism. The processes need to take place in a simultaneous manner and not following a strict sequential path.
 

Fermentation

Aerobic respiration

Glucose gets converted to ethanol during its partial breakdown.

Glucose breaks down completely, which leads to the formation of carbon dioxide.
