The total number of molecules of ATP produced during glycolysis is , which results in a net production of ATP.

The answer is "4 and 2 ".

Explanation:

The overall glycolysis ATP number is 4 of one hydroxyl group. In the first part of the glycolysis 2 ATP molecules are used, so that 2 ATP molecules are net gained. 2. In addition, 2 NADH atoms in the glycol are also created. This is why the total ATP molecules produced during metabolism are 4, resulting in a net output of 2 ATP.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
