Glycogen synthase
Which enzyme is responsible for cleaving α(1-4) bonds in glycogen degradation?
Glycogen phosphorylase
What is the cofactor needed for glycogen phosphorylase?
Vitamin B6
What type of bonds can glycogen phosphorylase cleave?
α(1-4) bonds
How many glucose residues away from a branching point can glycogen phosphorylase cleave?
4 or more glucose residues
What is the role of glycogen debranching enzyme in glycogen degradation?
Cleaves α(1-6) bonds
Which enzyme is responsible for adding inorganic phosphate in glycogen degradation?
Glycogen phosphorylase
Test your knowledge on the essential steps and regulatory enzymes involved in glycogen synthesis and degradation. This quiz will cover the committed step for glycogen synthesis, which involves adding UDP-glucose to the glycogen chain, and the regulatory enzymes for both synthesis and degradation, including glycogen synthase and glycogen phosphorylase. You'll also learn about the specific requirements for these enzymes, such as the need for pyridoxal, a vitamin. Challenge yourself and see how well you understand the intricacies
