A-level Biology Help >>>>> What are the elements of a plasma membrane impact the movement of substances within and out of cells Why is this regulation so important? Proteins and phospholipids control the movement of chemicals through the membrane, thus allowing it to become permeable in a specific way. This is essential as it permits cells to, for instance to maintain the water potential as well as remove waste materials or get nutrients. Together, proteins and phospholipids provide three forms of transport: 1.) diffusion, 2) faciliated diffusion, and three) the active transportation.
Phospholipids enable small molecules that are uncharged to pass across the membrane. For instance, oxygen or carbon dioxide. Furthermore, larger or charged molecules only pass through the membrane by an indirect diffusion process through channel proteins or carrier proteins. Both of these categories of proteins are designed for specific substances, such as such as sodium or glucose. Carrier proteins can perform the third kind of transport called active transport. Contrary to faciliated diffusion and diffuse, active transportation makes use of power in the form ATP to move substances across membranes in an intensity gradient.
