Example Questions

Example Question #265 : Catabolic Pathways And Metabolism

What is the term for the end of the a glycogen branch from which glucose residues are removed during degradation?

Possible Answers:

Non-bonding end

Bonding end

Non-reducing end

Degradation end

Reducing end

Correct answer:

Non-reducing end

Explanation:

The non reducing end of a glycogen branch is the end from which glucose units are removed during degradation of glycogen.

Example Question #1 : Other Glycogenolysis Concepts

Which of the following is an example of a catabolic reaction?

Possible Answers:

Protein synthesis

Gluconeogenesis

Glycogenolysis

DNA polymerization

Correct answer:

Glycogenolysis

Explanation:

A catabolic reaction is defined as a reaction used to break down a large molecule into smaller subunits. Of the following options, glycogenolysis is the only option where a larger molecule (glycogen) is broken down into smaller subunits (individual glucose molecules).

Example Question #1 : Other Glycogenolysis Concepts

Which one of the following can store the largest total amount of Glycogen in the human body?

Possible Answers:

Liver

Brain

Fat

Skeletal muscle

Correct answer:

Skeletal muscle

Explanation:

Glycogen is the storage form of glucose, and is more readily accessible than starches or fats. It is used for short-term supply of glucose and in starvation conditions is used up in a matter of hours. It is mainly stored in the liver and skeletal muscle. Glycogenolysis in the liver results in glucose release into the bloodstream, whereas in the muscle the glucose is immediately used up. The highest demand for the glucose is in the muscle, and that is where most of it is stored.
