    Q:

    		 The liver and muscle both play crucial roles in glycogen breakdown, but there are differences between the two. For example, muscle cells lack the enzyme glucose-6-phosphatase, which is required to pass glucose into the blood. Which of the following is FALSE regarding glycogen metabolism?
    		 

    A

    		 Although the muscle stores large amounts of glycogen, the liver is the major source of circulating glucose.

    B

    		 Only the glycogen stored in the liver can be made accessible to other organs in the body

    C

    		 While the muscle stores large amounts of glycogen, it lacks an enzyme to break down glycogen and release large amounts of glucose into circulation

    D

    		 While the liver stores large amounts of glycogen, it lacks an enzyme to break down glycogen and release large amounts of glucose into circulation
