pore protein 3. carrier protein SIMPLE DIFFUSION What is diffusion? Diffusion is the movement of particles from a high density region to a low density region. No energy is needed and no membrane involves in diffusion. The Dynamic Equilibrium Diffusion will continue until the concentration in all region is the same. When this happen‚ we say it has reached the dynamic equilibrium. Factors Affecting the Rate of Diffusion (How fast diffusion happens) Particles that Move Through

Premium Osmosis Diffusion Membrane biology
water-soluble substances cross the membrane through simple diffusion‚ facilitated diffusion and active transport. Osmosis is thought of as the diffusion of water from an area of high concentration of water molecules to an area of low concentration‚ across a partially permeable membrane. To define osmosis more accurately we define it in terms of water potential. Water potential is a measure of how easy it is for water molecules to move. Diffusion occurs because substances attract a ‘cloud’ of polar water
