Hey guys,

I am a little bit confused on how to calculate the number of ATP generated in a certain pathway.

The books say:

• Anaerobic glycolysis yields 2ATP/glucose by substrate-level phosphorylation.
• Aerobic glycolysis yields 2ATP/glucose plus 2NADH/glucose
• 2 Shuttles that can form ATP are;
  • Malate: 8ATP/glucose
  • Glycerol phosphate: 6ATP/glucose

Where are the ATPs comming from? I thought it had something to do with reoxidization of NADH to NAD and FADH2 to FAD.

I believe there might be a concept behind this which I do not understand. Also how would I calculate ATPs from another cycle if asked to do that?
