    About the Lecture

    The lecture Glycogen Metabolism by Kevin Ahern, PhD is from the course Metabolic Control.


    Included Quiz Questions

    1. Adrenaline and insulin have opposite effects in the liver
    2. Adrenaline stimulates liver to absorb glucose from the bloodstream
    3. Insulin stimulates muscles to produce glucose when needed
    4. Adrenaline and insulin work together to reduce blood glucose levels
    1. It is made by FBPase 2
    2. It is made by PFK2
    3. Insulin stimulates its production
    4. It favors glycolysis by activating phosphofructokinase (PFK)
    1. At high glucose levels in the blood, the insulin stimulates the excretion of glucose-1-phosphate from the liver cells
    2. The insulin binding to body cells stimulates the uptake of glucose from the blood and synthesis of glycogen
    3. The conversion of glucose-1-phosphate to glucose-6-phosphate occurs via enzyme phosphoglucomutase
    4. The insulin binding to liver cell receptors stops the release of glucose from liver cells by stopping the breakdown of glycogen due to deactivation of phosphorylase-a enzyme
    5. Phosphorylated protein kinase A enzyme activates phosphorylase kinase enzyme, whereas it has an inhibitory effect on the activity of glycogen synthase
