Plesae ASAP. thanku Which of the following is not true about the glutamate family of ligand-gated ion channels? a. members are AMPA, kinase, and NMDA channels b. they are cation permable c. channels subunits have 3 full transmembrane doamins d. they require 5 subunits to amke a functional channel

Please ASAP. Thank you. The figure below shows that after the application of ouabain, the rest potential approaches 0 mV. Which of the following is the most likely explanation for this observation.

need this to be corrected. answers are provided but need to know if they are correct or incorrect.

Please 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?

In he or sti ne eti 39. Why do activated states rarely occur at physiological temperatures? How do cells overcome this?
