CEM 311 Lecture Notes - Lecture 33: Dihydroxyacetone Phosphate, Enol, Phosphoglycerate Kinase
Document Summary
Phosphoglucoisomerase catalyzes the isomerization of glucose-6-phosphate to? fructose-6-phosphate. It has a higher affinity for the active site than the allosteric site. The mechanism for the aldolase reaction proceeds through which intermediate? enolate anion of dihydroxyacetone phosphate. Which enzyme is not in the first phase of glycolysis? phosphoglycerate kinase. The free energy available from the re-arrangement of chemical bonds in the conversion of one mole of glucose to two moles of lactate is conserved in the formation of four moles of atp. Note the net production is two moles of atp. This answer isincorrect because the nadh produced in glycolysis will be oxidized during the conversion of pyruvate to lactate. Note that aerobic glycolysis will have a net production of two moles of atp and two moles of nadh. In the mechanism of glyceraldehyde-3-phosphate dehydrogenase, the conversion of the hemithioacetal to the thioester involves:
