Glycolysis produces pyruvate which is functioning normally if only the ETC (electron transport) stopped working because the ETC happens <u>AFTER</u> glycolysis, hence pyruvate is being produced and used at a normal rate (no change). NADH is produced in the cellular respiration stage <u>PRIOR</u> to the ETC so it is being created at a normal (or average) rate, however, it is not being used and split properly (meaning, not enough) in the ETC stage hence it's concentration increases. H+ decreases because it cannot be made if the prior step(s) were not complete.
