Example Question #192 : Carbohydrate Metabolism
What is the term for the end of the a glycogen branch from which glucose residues are removed during degradation?
Degradation end
Non-bonding end
Non-reducing end
Bonding end
Reducing end
Non-reducing end
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?
Protein synthesis
Gluconeogenesis
Glycogenolysis
DNA polymerization
Glycogenolysis
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 #192 : Carbohydrate Metabolism
Which one of the following can store the largest total amount of Glycogen in the human body?
Liver
Brain
Fat
Skeletal muscle
Skeletal muscle
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.
