Web3) An increase in the partial pressure of carbon dioxide (from the working muscles) 4) An increase of a byproduct molecule from glycolysis known as 2,3-BPG. This shifting of the curve to the RIGHT (from these 4 factors) is referred to as the Bohr effect. Christian Bohr is the scientist who first explained this occurence from aerobic exercise. Web2) 1,3-BPG --> 3-phosphoglycerate 3) Rearrangement 4) Dehydration to form PEP ... Does Stage 2 of glycolysis happen twice. Yes. Net reaction of glycolysis. 1 Glucose + 2 ADP + 2 Pi + 2 NAD+ --> 2 Pyruvate + 2 ATP + 2 NADH + 2 H+ + 2 H2O. Net gain of ATP. Net gain of ATP is only 2 because we lost two ATP at steps 1 and 3 of Stage 1 of glycolysis.
