no but i will figure it out not that educated to read that mess and understand it but thanks for trying anyways

It's not that hard... only look at the red bordered yellow stars with the text ATP. You see first step takes 1 ATP and converts it to ADP, in the third step the same happens. So we have a net loss of 2 ATP. Now in the bottom row you see 2 times the reversed process, ADP being converted to ATP. these to happen 2 times.

In short words: Glycolysis produces 4 ATP and takes 2 ATP, so the net gain is 2ATP.
