Document Summary

D-glucose + 2 adp + 2 pi + 2 nad+ . 2a: glucose is phosphorylated to form glucose- Gap (making 2 separate gap molecules: both gap molecules are converted to. Glycerate-1,3-bisphosphate (g1,3bp) and produces requires phosphate and nad. Nadh: g1,3bp is dephosphorylated to form glycerate-3-phosphate (3gp) 2b (2gp: 3gp is converted to glycerate-2-phosphate, 2gp is then converted to phosphoenolpyruvate (pep, pep is then dephosphorylated to produce pyruvate, and again, a molecule of atp is produced (one from each pep, making 2 tota. Step 1 phosphorylation of glucose: when glucose (and other 6-carbon sugars) enters the cell, 10 steps of glycolsis it is phosphorylated in the cytoplasm by enzymes called hexokinases. This modification prevents the monosaccharides from leaving the cell and the reaction is not reversible under physiological conditions. Hexokinases i, ii, and iii are saturated at low concentrations of glucose and are inhibited by.
