Question

In my bio class we're learning about cellular respriation. With Glycolysis, Krebb's Cycle, and Electron Transport Chain how many ATP's are made by each one. Please help!!

Answer 1

Energy yield per glucose molecule can be either 36 or 38 total ATP

2 from glycolysis
2 from Krebs cycle
and either 32 or 34 in Electron Transport System depending on the situation it was conducted.
