Webb(i) Simple diffusion is when ions or molecules diffuse from an area of high concentration to an area of low concentration. Examples of simple diffusion are the gaseous exchange that occurs during photosynthesis, and the evaporation of water in plants during transpiration. Webb8 nov. 2024 · Simple diffusion occurs by the diffusion of molecules, such as O 2 and CO 2, across the hydrophobic core of the membrane (Figure 2.7. 3 ). Therefore, no ATP is required for this type of diffusion across the membrane, it is simply a matter of molecules moving down a concentration gradient.

WebbDiffusion only happens when there is a: 1) concentration gradient 2) and a net movement of particles any change requires ____________ energy How come there cannot be diffusion in a solid? Diffusion requires kinetic energy of the particles to create movement (solid particles only vibrate) Does diffusion require energy input? no WebbSimple diffusion is an example of passive transport that occurs when electrochemical potentials vary on both sides of a permeable barrier. In this type of diffusion, very small molecules can move through gaps. Location – between the various phospholipid molecules in cell membranes.
