To discuss:
The similarities and differences between facilitated diffusion and active transport.
Introduction:
Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. Peripheral proteins are generally found on the membrane surface and are temporarily attached to one face of the plasma membrane. Membrane proteins that traverse the entire cell membrane alone can serve as a membrane channel. A membrane channel aids in the transfer of solutes from one side of the cell membrane, which is selectively permeable, to the other side of the membrane. Such integral proteins are called as transmembrane proteins. Carriers are transmembrane proteins present in the plasma membrane, which facilitates the transfer of substances, including electrolytes and glucose.

- What is NOT true about diffusion: 1. A form of passive transport. 2. Uses adenosine triphosphate to transport substances across the plasma membrane. 3. Tendency of molecules to move from an area of higher concentration to an area or lower concentration. 4. Classified as either facilitated diffusion or simple diffusion.arrow_forwardCold HOT Effect of Temperature on the Rate of Diffusion Solutes move within a cell's cytoplasm largely because of diffusion. However, the rate of diffusion is affected by such factors as temperature and the size of the solute molecule. Observe the effect of different temperatures on the rate of diffusion by watching the video above. Temperature Homework • Unanswered At which temperature did solutes dissolve the fastest?
