ECON 1 Lecture Notes - Fish Oil, Lipid Bilayer, Phospholipid
Document Summary
When the cell is not generating impulses not transmitting neurotransmitters = at rest. The cytosol (intracellular fluid) on the inside of the membrane has a negative electrical charge, everything outside the membrane has a positive electrical charge. Resting membrane potential = the difference in electrical charge across the membrane: the membrane potential is the voltage across the membrane (mv, typically it is -65 mv. Resting potential is when the neuron is in reversible state, the state can change but the neuron is at rest. Phospholipids: water-loving (face to water)= hydrophilic phospholipids, water-hating (face away from water) hydrophobic phospholipids. These phospholipids have polarity which is a strong bond that keeps them together. Membrane has a double layer of phospholipids = phospholipid bilayer maintains structure of membrane: keeps the cytosol inside separates intracellular and extracellular fluids. Mainly exist out of water, in the water ions are dissolved because water molecules are polar (one side positive & one side negative)
