Unformatted text preview: glc I II Fructose 1,6 bisphosphate DHAP GAP III 1,3 bisphosphoglycerate IV phosphoenolpyruvate pyruvate GLYCOYSIS a. Enzyme requires ATP as a substrate b. Form of glucose that readily crosses membranes, particularly actively metabolizing cells c. Action of this enzyme commits glc to catabolism to pyruvate d. Enzyme catalyzes an easily reversible aldose<=>ketose isomerization e. Enzyme requires a keto group at carbon 2 to form a transient ester linkage with substrate f. Enzyme catalyzes both an oxidation and a phosphorylation g. Enzyme requires ADP as a substrate h. High energy substrate when converted to product yields direct chemical energy i. Enzyme catalyzes and oxidative phosphorylation and generates ATP via substrate level phosphorylation j. Enzyme can be classified as a transferase or group transferase k. Enzyme has a Go > 0 under standard conditions, but G in the cell is negative because the products are rapidly removed and [product] remains low l. Enzymatic reaction in stage I where Go and Gcell are both << 0...
