Document Summary
10% of the total energy in glucose is harvested (better than fermentation, but still not that much) takes place entirely in the cytosol: the rest of respiration takes place in the mitochondria matrix, electron transport chain takes place on the inner membrane of the mitochondria, stage 1: energy investment, uses 2 atp to add phosphate groups to the glucose molecule to get it to a high energy state, stage 2: energy recovery, produces 4 atp and nadh (reduced electron carrier) Regulation of glycolysis: glucose can cross membranes until it is phosphorylated (cid:224) makes it so it"s stuck in the cell for glycolysis, glucose is converted into fructose (reversible, once fructose is converted to phosphofructokinase, it is committed to continue down the glycolysis pathway, key regulatory step, phosphofructokinase can be combined with glcnac to stop glycolysis in cancer cell metabolism, allows the glucose to be taken away from glycolysis to make into nucleotides.
