For the 3 central metabolic pathways (glycolysis, transition step, and transition step, and Krebs cycle ) and cellular respiration using the electron transport chain, state the principal starting substrate, the end product (if there is one), the amount of ATP generated by substrate-level phosphorylation, and the amount of ATP that can be generated through reducing power. Compare and contrast substrate levels and oxidative phosphorylation. What happens in prokaryotes that lack an electron transport chain? How do they generate ATP?
