Diabetes is a disease where the body is unable to produce enough insulin, which is a protein produced in the pancreas to help lower the levels of blood glucose. Which
two organelles are most responsible for producing insulin in the pancreas?

Explanation:

The cells which produce insulin are beta cells. These cells are distributed in a cluster of cells in the pancreas called the Islets of Langerhans, named after the anatomist who discovered them.

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.
