(a)
To determine:
Introduction: The transport of sodium and potassium ions across the membrane is an active transport process, which involve the hydrolysis of adenosine triphosphate (ATP) to provide the energy. It is done with the help of enzyme Na+/K+-ATPase. Most cells of human body pump potassium ion inside the cell to maintain internal potassium ion concentration which is 30 to 40 times the external concentration.

The following question involves the ligand binding to a receptor and the receptor's response to that ligand. What ligand concentration would be required for a full agonist with a KD of 8 nM to achieve a response of 0.75?arrow_forwardDefine resting membrane potential and describe its electrochemical basis. Briefly discuss changes to resting membrane potential. Provide specific examples of how the 4 essential concepts relative to resting membrane potential or disruption of resting membrane potential.arrow_forward
- Calculate the maximum ratio that can be achieved by the plasma membrane Na+-glucose symporter of an epithelial cell when [Na+]in is 12 mM, [Na+]out is 145 mM, the membrane potential is −50 mV (inside negative), and the temperature is 37 °C.arrow_forwardGraph of membrane potential versus time The graph above represent time in milliseconds. At what time (in milliseconds) is the inside of the neuron the most positive and why? Explain why the membrane potential changes at X. Explain what is happening at point C to the sodium and potassium ions and how this is affecting the membrane potential. Describe two things that contribute to the resting membrane potential.arrow_forwardA. Why small children (generally before and around the stage of toddlers) tend to fall, while later on they will develop improved mobility. Briefly explain this limited mobility in their early years in terms of the formation and maturation of the different components of the nervous system structures. B. How does a typical skeletal muscle and a typical neuron behave differently when they get depolarized? If you block the achetalcholine receptors on the plasma membrane of these two types of cells, what would be the effect on the response of each of these two cell types? why.arrow_forward
- Please ASAP. Thank you. If the Cl- concentration outside of cells is 10 mM and inside of cells is 10mM, what would the Cl- equilibrium potential be? When the membrane is at +10mV. The chloride flows in which direction?arrow_forwardCalculate the equilibrium membrane potentials to be expected across a membrane at 37 ∘C, with a NaCl concentration of 0.50 M on the "right side" and 0.08 M on the "left side", given the following conditions. In each case, state which side is (+) and which is (−). Membrane equally permeable to both ions.arrow_forward37.Given an intracellular concentration of 120mM and an extracellular concentration of 15mM, calculate the Nernst Equilibrium Potential for K+ in mV 38 Given an intracellular concentration of 2mM and an extracellular concentration of 107mM, calculate the Nernst Equilibrium Potential for Cl- in mV 39 A cell has an actual membrane potential (Em) at rest of -75mV. The equilibrium potential for Na+ is +120mV and the equilibrium potential for K+ is -95mV. Calculate the net driving force for Na+ in mV.arrow_forward
- For this practice problem, would the answer be c)NaCl? My reasoning behind this is because molecules under 100 Da can use simple diffusion, while nonpolar molecules and larger molecules like benzene can use channels via facilitated diffusion. However, NaCl dissociates into ions and cannot readily use diffusion?arrow_forwardFill in the blank :- The depolarization phase of action poten:-tials in neurons is due primarily to.........
