Hi, can someone help please. Thank you!

Please ASAP. Thank you. A hypothetical neuronal cell shows the following intracellular and extracellular concentration of sodium, potassium, calcium, and chloride ions.   Extracellular concentration (mM) Intracellular concentration (mM) (Ion)out/ (Ion)inside E ion at 37 oC Sodium ion 420 60     Potassium ion 25 420     Calcium ion 16 0.4     Chloride 565 45     How does increase in the extracellular potassium concentration to 250 mM affect the Nernst potential? Why?

C, D correct answer. I need explanation. Asap

Dear Expert. Thank you for your advice, which is good and helpful. I note that your answer is "when 3 binding sites have been occupied the activity of these receptors is maximum." However, I also note that for a similar question (see below) on α7 nicotinic Acetylcholine Receptor (nAChR) also gives the same answer, ie. at least 3 agonist binding sites should be occupied.  Another Question - "To maximize the activity of an α7 nAChR, how many agonist binding sites should be occupied." I understand that in α7 nAChR, binding to two sites is more effective and binding to three sites is most effective for activation. On the other hand, binding to four or five sites in the nAChRs of chromosome 7 speeds up desensitization more than activation. Therefore, to maximize the activity of an α7 nicotinic Acetylcholine Receptor (nAChR) is also "3 sites". Am I right?

Can Please Help Me: Bio- Chemistry 60 minutes only the given time. Wish you could help me. I will give UPVOTE and GOOD FEEDBACK. QUESTION/// Diisopropyl fluorophosphate (DFP) inhibit acetylcholinesterase activity by reacting covalently to a serine residue found within the active site of the enzyme. The physiological effect of this inactivation is interference with neurotransmitter inactivation at the synapses of nerves, resulting in the constant propagation of nerve impulses, which can lead to death. What type of inhibitor is DFP? Explain. ///QUESTION
