Question

Match the items with the appropriate option.

Answer 1

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.
