Plasma Membrane Selective Permeability

This lecture covers the selective permeability of the plasma membrane, discussing the passage of various molecules such as oxygen, carbon dioxide, glucose, and ions. It also explores osmosis, aquaporins, osmotic pressure, and the impact of different tonicity levels on cell volume and function. Additionally, it delves into ion channels, membrane potential, and the role of K+ channels in generating a diffusion potential. The presentation concludes with an overview of EEG, ECG, and the resting membrane potential in cells.
