Glycogenolysis

(1 min)
A metabolic process that converts glycogen from the muscles and liver to its monosaccharide form, glucose.

(30 sec)

True or False:

Low levels of ATP within live cells trigger the glycogenolysis process.

• Heart and liver

• Kidney and muscles

• liver and muscles

• Kidney and liver

The two main regulating enzymes of glycogenolysis.

• Glycogen phosphorylase and phosphorylase kinase

• Adenyl cyclase and cAMP

• phosphoglucomutase and glycogen phosphorylase

• Acid α-glucosidase and phosphoglucomutase

This mechanism acts as an instant source of energy during the newborn stage.

• glycogenolysis

• autophagy-dependent mechanism

• glycolysis

• α-glucosidase

(45 sec)

An enzyme that converts glucose-1-phosphate (reversibly) into glucose-6-phosphate in the liver, kidney, and intestines.

• adenyl cyclase

• phosphorylase kinase

• Phosphoglucomutase

• glycogen phosphorylase

Glycogen breakdown in the muscle cells serves as an instant resource of glucose-6-phosphate for the process of glycolysis, which produces energy for muscle contraction. What is the other term for muscle cells?

True or False:

The liver immediately utilize the glucose that is created during glycogenolysis in the liver.

• True

• False
