Please ASAP. THankyou. Question 17 If you completely inhibit the Na+/K+ ATPase, which of the following would you most likely observe?     Decrease in Na+/Ca++ exchanger activity       The Nernst potential for K+ would become more positive       Intracellular Na+ concentration would increase       All of the above

Energy is required to do work. What type of work is being done by the Na+/K+ ATPase that allows it to maintain a steady state in the neuron? 1. both chemical and transport work 2. Mechanical work 3.chemcial work 4.transport work

Pleasea asap. thanku You measure the membrane potential and find that it does not change from time X to time Y. However, you find that current across the membrane has increased by a factor of 4 from time X to time Y. What most likely happened between time X and Y?

Assighment. Create a diagram which illustrates the typical signalling mechanism of action of each of the four common classes of receptor (e.g. kinase-linked receptors etc.) and possible routes of communication (autocrine etc.). Your diagram should show the specific molecules involved, the mechanisms of signal transduction and indicate the different pathways that are activated. It should include a specific example of a receptor, ligand and signalling pathway for each general class. Include as wide a variety of ligands and modes of action as you can. For each of the examples describe the mechanism of action in the form below. DO NOT use any of the ligand-receptor combinations provide to you in the Learning Materials to date - research and create a diagram for a novel pathway instead!
