So I have a question I'm kind of struggling to understand. I feel like the answer is probably pretty simple.

When ribose is catabolized to generate energy, it can enger glycolysis as fructose 6 phosphate. How much ATP would be made from One mole of ribose going all the way through glycolysis, TCA cycle, and the electron transport chain and oxidative phosphorylation?

If glucose gives 30, would this just give 31 because it skips the step where glucose is changed into glucose 6 phosphate (which uses ATP)?

You would still use 1 mole to ATP to phosphorylate 1 mole of ribose into ribose-5-phosphate

Oh I guess I didn't consider that! We only went over the main process, so I wasn't sure if it would need to change to ribose-5-phosphate! Thank you!
