26. What about the structure of a fat molecule makes it useful for a cell and why? The large number of carbon-hydrogen bonds allow for the storage of energy.
Fats serve as enzymes in the process of digestion.
The glycerol portion of the fat molecule is used to release energy
The fatty acid part of fats help digest food in cellular respiration.

the large number of carbon-hydrogen bonds allow for the storage of energy

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.
