WebbThe plasma membrane of the neuron is highly permeable to K +, and in fact the recorded membrane potential of most neurons (−60 to −75 mV) is close to that predicted by the Nernst equation for K +. However, it is not exactly the same, because K + is not the only ion affecting the membrane potential. WebbCorrect answer is option CExplanation for correct option: The fluid mosaic model of Singer and Nicolson (1972), is now widely accepted as best explaining the properties of the cell membrane. This model assumes that there is a continuous bilayer of phospholipid molecules in which are embedded globular proteins.
Webb11 apr. 2024 · It consists of a phospholipid bilayer that acts as a physical barrier to separate distinct intracellular compartments (such as the endoplasmic reticulum (ER), Golgi apparatus, and nucleus), and separates the cell from the external environment [ 1 ].
