Acarbohydrate molecule is (2 points) a macromolecule made of amino acids that provides structure for a cell and is not soluble in water made up of a chain of monosaccharides that transport genetic coding from one end of the cell to another made up of the monosaccharide glucose and serves as an energy reserve in plants and animals a chain of amino acids that can be used for protein synthesis, protection, and increasing reaction speeds

A carbohydrate is a biological molecule consisting of carbon, hydrogen, and oxygen

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.
