Concept #1: Allosteric Regulation of Glycogen Phosphorylase a

Practice: A patient comes into your clinic suffering from anorexia nervosa. Her mother brought her in concerned as the patient has not eaten in over 3 days. She has the classic presentation including low body weight, decreased muscle mass, decreased glycogen, and decreased fat stores, and she is anemic (low red blood cell count). What would be the expected phosphorylation state and activity of the patient’s liver glycogen phosphorylase?

Concept #2: Allosteric Regulation of Glycogen Phosphorylase b

Practice: Muscle glycogen phosphorylase displays multiple modes of allosteric regulation. Which of the following is true?
