I have to correct you... Glycolysis realeses 4 ATP for a net gain of 2 :D

What do you mean releases 4 molecules? from what i know, more energy is released, but only 2 molecs is formed cause the rest is lost through heat

I think what thank.darwin was trying to say is 2 ATP is used at first. And then 4 ATP is produced. So the net gain is 2 ATP.
Did I get it right, thank.darwin? :)

You lost me there... First of all, what do we understand by net gain?

The final gain.
Like you earned 4 dollars and then you spent 2 dollars. your net gain is 2.
ATP is like that.

A better analogy would be like if you were cashing a check at a store instead of a bank. They charge you.

Let's say that you have a check written out to you for $4.00. The store charges you $2.00 to cash it. So you walk away with $2.00.

2 ATP is used at the begining of the process.

b) Which cells are those?

Answer:

a) Under "anaerobic" conditions when oxygen is not (or less) available.
