More sodium outside of the cell More potassium inside the cell These are their chemical gradients and they DO NOT change Electrical Gradients or membrane potentials DO change Equilibrium potential for sodium is +60mV Equilibrium potential for potassium is -90mV Osmosis is movement of water A cell loses mass; you know that water left, which tells you that the inside of the cells if hypotonic to the outside of the cell because the water goes to the higher concentration in order to dilute it Explain difference between hydrophilic and hydrophobic messengers and their placement? Membrane is mostly hydrophobic, so hydrophobic messengers can dissolve right through the membrane, so their receptors are located inside the cell while the hydrophilic messenger receptors are located outside of the cell Membrane potential is the same as electrical gradient Chemical gradient is the same as concentration gradient Second messengers are only found with hydrophilic messengers because their
