The major product from the action of glycogen phosphorylase and the debranching enzyme glucantransferase is ________. 1) fructose-6-phosphate 2) UDP-glucose 3) glucose-1-phosphate 4) glucose-6-phosphate

Respuesta :

Answer:

Glucose-1-phosphate

Explanation:

  • Glycogen is the major storage component in animals, that stores the excess glucose for future use.
  • When glucose levels go down below normal levels, the hormone glucagon is produced to trigger the liver cells to break down glycogen to glucose that is then released to restore normal blood sugars.
  • The break down of glycogen to glucose is known as glycogenolysis that is catalyzed by the enzymes glycogen phosphorylase and the debranching enzyme glucantransferase.
  • Debrancing enzyme breaks down the glycogen branches while the glycogen phosphorylase breaks down shorter chains of glycogen to glucose-1-phosphate.
  • Consequently, glucose-1-phosphate is converted to glucose-6-phosphate and then to glucose.

glucose-1-phosphate

Further Explanation

Glycogenolysis

The glycogen breakdown must first be broken down to be obtained as energy. Which is the process of glycogenolysis occurs in different pathways. With the help of the enzyme phosphorylase. Then the inorganic phosphate will release the rest of the sentence to get the phosphate D-emission.

So it can be interpreted that the process of glycogenolysis is a glycogen breakdown process that occurs through different paths.

The process that begins with the transition molecule will end with the formation of lactic acid. As for the second phase, it will begin through a triosephosphate oxidation process until lactic acid is formed.

Gluconeogenesis

The process of gluconeogenesis can occur as available energy sources are no longer available. If fat in the body is also no longer available, the process of protein breakdown will occur. The process that occurs in gluconeogenesis or the formation of new sugars is that lactic acid will be converted back into a transition through a series of reactions. Although gluconeogenesis is a synthesis process, it is not a reverse process of glycolysis.

Glucose + ATP becomes hexokinase-6-phosphate + ADP.

Fructose-6-phosphate + ATP phosphoryuctokinase to fructose 1.6 diphosphate + ADP.

Phosphoenolpyruvate + ADP pyruvate kinase to pyruvic acid + ATP

With these three irreversible reactions, the process of gluconeogenesis can proceed through other reactions such as phosphoenolpyruvate formed from pyruvic acid with the formation of oxaloacetic acid.
