WebTotal ATP production is 38 ATP per glucose. Note 1: Some books state 36 ATP per glucose but this occurs in cells that convert the 2 NADHs made in glycolysis into 2 FADH2s when they enter the mitochondria where Krebs cycle and ETC occur. (It is a transporter phenomenon and has nothing to do with using ATP.) WebA net of two ATP are produced through glycolysis (four produced and two consumed during the energy-consuming stage). However, these two ATP are used for transporting the NADH produced during glycolysis from the …

So it … WebBasically, insulin promotes anything that will decrease blood glucose levels. This can happen in two ways: either converting glucose--> pyruvate (glycolysis) or by converting glucose-->glycogen (glucogenesis). Glucagon does the opposite, it promotes any pathway that will increase blood glucose levels. That is either by converting glycogen ...
