Which monomer serves as the building block of glycogen, a polymer made up of many glucose molecules?

The correct answer is glucose.

Glycogen is a polysaccharide composed of multibranched glucose units (about 8–12 glucose units) linked by the glycosidic bonds. It is a form of energy storage in the body, especially in the liver cells in the form of granules. When there is a sudden need for glucose, glucose from the glycogen can be rapidly mobilized. It also plays an important role in the glucose cycle.

Monosaccharide

Explanation:

Monosaccharides are the building blocks of sugars and contain carbon, hydrogen, and oxygen in their molecular formula.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
