Pyruvate kinase enzyme class
WebFeb 2, 2010 · Speculative possibilities include mitochondrial redox effects, which could affect the state of cytoplasmic reducing equivalents, with consequent effects on myriad enzyme systems and kinases. These could then alter fuel selectivity at notable steps, such as AMPK kinase, pyruvate dehydrogenase, phosphofructokinase, or others. WebChemistry questions and answers. To which class of enzymes does each of the following belong? 1. Phosphofructokinase - p. 383 ( #3 glycolysis) 2. Triose phosphate isomerase - p. 383 ( #5 glycolysis) 3. Pyruvate kinase - p.384 ( #10 glycolysis) 4.
