The key difference between simple diffusion and facilitated diffusion is the difference of transport proteins. In simple diffusion, molecules passively move down their concentration gradient directly through the plasma membrane without any help. While in facilitated diffusion, the transport of molecules occurs by the use of integral membrane proteins that form selective channels or carriers. … Read more
The main difference between simple diffusion and osmosis is the difference of the type of molecule being transported and the driving force behind the movement. Any molecule with kinetic energy, such as small molecules, gases, and even some ions, can move through diffusion while Osmosis specifically involves the movement of water molecules across a semipermeable … Read more
Simple diffusion is considered a physical change because it simply redistributes particles randomly without changing their chemical properties. This spontaneous particle dispersal relies only on intrinsic particle motion and concentration gradients, not the formation or destruction of chemical bonds. Refrences: [1] [2] While chemical changes involve old chemical bonds being broken and new ones formed, … Read more
What is Simple Diffusion? Simple diffusion is a form of diffusion that does not require the help of membrane proteins. In simple diffusion, particles or substances move from areas of higher concentration to areas of lower concentration, going “downhill” due to concentration gradient. It does not involve membrane proteins to help transport the substances across … Read more
