Vedclass · Answer

(D) $1$. At the resting stage,the inner surface of the axonal membrane is negatively charged due to the presence of $K^+$ ions and negatively charged proteins.$2$. When a stimulus is applied,the membrane becomes permeable to $Na^+$ ions,causing an influx of $Na^+$. This leads to depolarization,where the inner surface becomes positively charged.$3$. Subsequently,the membrane permeability to $Na^+$ decreases and $K^+$ permeability increases,leading to repolarization where the inner surface returns to a negatively charged state.$4$. Thus,the sequence of charges on the inner surface is negative (resting),positive (depolarized),and negative (repolarized).
