The glycolysis ledger

A list gives the steps of glycolysis that change ATP or NADH. Each row says how much ATP and NADH it changes for one PGAL or one hexose, and how many times it runs for each glucose. You will add up the ledger.

The idea. A minus sign means that ATP is used. A plus sign means that it is made.

Your tasks.

1. Set used to the ATP that is used for one glucose.
2. Set made to the ATP that is made for one glucose.
3. Finish net_atp. It gives the net gain of ATP for glucose glucose molecules.
