Question

What are the assumptions made during the calculation of net gain of ATP?

Answer 1

For theoretical calculation of ATP molecules, various assumptions are made, which are as follows.

(a) It is assumed that various parts of aerobic respiration such as glycolysis, TCA cycle, and ETS occur in a sequential and orderly pathway.



(b) NADH produced during the process of glycolysis enters into mitochondria to undergo oxidative phosphorylation.

(c) Glucose molecule is assumed to be the only substrate while it is assumed that no other molecule enters the pathway at intermediate stages.

(d) The intermediates produced during respiration are not utilized in any other process.

Answer 2

Answer:

Assumtions made during the calculation of net gain of ATP

Explanation:

ATP OR ADENOSINE TRI PHOSPHATE is an energy rich molecule is produced by various catabolic process. The assumtions that are made are

1 ATP is generated from Aerobic respiration that includes Glycolysis,TCA cycle and Electron transport chain.

2 The byproduct Such as NADPH, FADH2 generates 3molecules and 2 molecules of ATP respectively.

3  some ATP molecules are made from substrate lebel phosphorylation for example conversion of 1,3 bisphosphoglycerate to 3 phosphoglycerate.

4 1 molecule of glucose is taking part in the aerobic respiration to generate 38 molecules of ATP.
