BIOL 2083 Study Guide - Dihydroxyacetone Phosphate, Lactate Dehydrogenase, Anaerobic Glycolysis
Document Summary
Alcoholic fermentation: the anaerobic pathway that converts glucose to ethanol. Aldolase: in glycolysis, the enzyme that catalyzes the reverse aldol condensation of fructose-1,6- bisphosphate. Anaerobic glycolysis: the pathway of conversion of glucose to lactate; distinguished from glycolysis, which is the conversion of glucose to pyruvate. Committed step: in a metabolic pathway, the formation of a substance that can play no other role in metabolism but to undergo the rest of the reactions of the pathway. Glyceraldehyde-3-phosphate: a key intermediate in the reactions of sugars. Glyceraldehyde-3-phosphate dehydrogenase: an important enzyme in glycolysis and gluconeogenesis. Glycolysis: the anaerobic breakdown of glucose to three-carbon compounds. Kinase: a phosphate-transfer enzyme, with atp as the usual source of the phosphate. Lactate dehydrogenase: an nadh-linked dehydrogenase that catalyzes the conversion of pyruvate to lactate. Phosphofructokinase: the key allosteric control enzyme in glycolysis; it catalyzes the phosphorylation of fructose-6- phosphate. Pyruvate kinase: the enzyme that catalyzes the final step common to all forms of glycolysis.
