Answer:
Breakdown of glucogen.
Glycogen phosphorylase of muscle and liver, which catalyzes the reaction
(Glucose)n + Pi ----> (glucose) n-1 + glucose 1-phosphate
Shortened glycogen chain
* acyl-CoA dehydrogenase
Dehydro genation of fatty acyl–CoA produces a double bond between the alpha and beta carbon atoms
Regulatory Enzyme of fatty acid breakdown
*Pyruvate dehydrogenase complex
Pyruvate derived from glucose and other sugars by glycolysis, is oxidized to acetyl-CoA and CO2 by the pyruvate dehydrogenase (PDH) complex, located in the mitochondria of eukaryotic cells and in the cytosol of bacteria.
Pyruvate converted to acetyl CoA
*Citrate synthase
The first reaction of the citric acid cycle is the condensation of acetyl-CoA with oxaloacetate to form citrate, catalyzed by citrate synthase:
Citric acid cycle.
* Lactate dehydrogenase
When animal tissues cannot be supplied with sufficient oxygen to support aerobic oxidation of the pyruvate and NADH produced in glycolysis, NAD+ is regenerated from NADH by the reduction of pyruvate to lactate.
Anaerobic respiration
*Phosphofructokinase
Glucose 6-phosphate can flow either into glycolysis or through any of several other pathways,
including glycogen synthesis and the pentose phosphate pathway. The metabolically irreversible reaction catalyzed by PFK-1 is the step that commits glucose to glycolysis.
Regulatory enzyme of glycolysis
*succinate dehydrogenase
Part of both the citric acid cycle and oxidative phosphorylation
*adenylate cyclase
Converts ATP to cAMP
*Glucose 6-phosphate dehydrogenase
Glucose 6-phosphate dehydrogenase catalyzes the first step in the pentose phosphate pathway, which produces NADPH.
Pentose phosphate pathway
*Glucose 6-phosphatase
Glucose 6-phosphate is dephosphorylated by glucose 6-phosphatase to yield free glucose.
