Which of the following terms describes glycogen catabolism?
Glycoproteins
Glycosaminoglycan
Glycogenolysis
Gluconeogenesis
The Correct Answer is C
a. Glycoproteins: Glycoproteins are proteins that have carbohydrate groups attached to them and are not related to glycogen breakdown.
b. Glycosaminoglycan: Glycosaminoglycans are long polysaccharide molecules involved in building connective tissues, not in glycogen catabolism.
c. Glycogenolysis: Correct. Glycogenolysis is the process of breaking down glycogen into glucose to be used for energy.
d. Gluconeogenesis: Gluconeogenesis is the process of producing glucose from non-carbohydrate sources, not the breakdown of glycogen.

a. Forming the contractile component of the digestive, urinary, and reproductive systems: This describes smooth muscle, not skeletal muscle.
b. Contracting to cause involuntary muscle movements: This is a characteristic of smooth and cardiac muscles. Skeletal muscle is primarily involved in voluntary movements.
c. Pumping blood throughout the body: This is the function of cardiac muscle, not skeletal muscle.
d. Shivering for heat production: Correct. Skeletal muscles generate heat through shivering, which is an involuntary contraction response to cold.
Correct Answer is B
Explanation
a. Cell body: The cell body is the main part of the neuron containing the nucleus and other organelles. It does not directly transmit impulses.
b. Axon: The axon is a long fiber that carries electrical impulses away from the cell body towards other neurons or muscles.
c. Synapse: A synapse is a junction between two neurons where nerve impulses are transmitted. The axon of one neuron transmits an electrical signal to the dendrite or cell body of another neuron across a small gap. Neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, either exciting or inhibiting it.
d. Dendrite: Dendrites are short, branching fibers that receive signals from other neurons and transmit them towards the cell body.
