Answer the following two questions:A.Explain why the EPSP is larger if the membrane potential becomes more hyperpolarized than the resting membrane potential.B.If a ligand gated channel is a non-specific cation channel, describe the nature of the current (which ions) will flow through it if activated at the resting membrane potential and why?
Ans- in hyperpolarized state the cell possess more Cl ion along with Ca2+ ions and these Ca2+ and Na+ ions are responsible for the production of EPSP while in resting membrane potential the more Na+ ions are outside of cells and more K+ ions are inside the cells which is not favorable for the EPSP.
Ans-B the non specific cation channel will allow the influx of positively charged ion into the cell. During rest potential only K+ ion channel are activated so it will only allow the inflow of the K+ ions.
