What would be the consequence of the loss of the gene that encodes glycogenin in the liver? Liver glycogen will be less readily degraded. (The mobilization of liver glycogen will be impaired.) Glycogen will not be degraded unless a hormone induced pathway coverts the phosphorylase. Very little glycogen will be synthesized. Little glycogen would be present in the liver due to increased degradation. Which of the following reactions are nonspontaneous? FAD. 24" 2 FADH2 NADH + H → 20' NAD...
