Is facilitated diffusion?
Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane

Why do most substances have to be assisted through the plasma membrane?
The plasma membrane is made from tightlypack phospholipids. The plasma membrane prevents polar molecules and large molecules from diffusing freely. Fatty (lipophilic) molecules can easily pass through. since cells often need water soluble materials such as water and sugars, transporters and pores need to be made out of proteins to let those molecules through. One of the most important pumps is the Na+/K+ ATPase pump which maintains gradients of sodium and potassium across the cell membrane
What substance crosses the cell membrane by simple diffusion?
Non-polar molecules such as oxygen, carbon dioxide, and water can cross the cell membrane by simple diffusion. These molecules can move freely through the lipid bilayer without the need for a transport protein.
Assisted transport of a molecule across the cell membrane without an expenditure of energy is known as?
Passive transport. It relies on the natural movement of molecules from an area of higher concentration to an area of lower concentration, following the concentration gradient. Examples include diffusion and facilitated diffusion.
How do molecules, assisted by proteins, move from areas of high concentration to low concentration?
Molecules move from areas of high concentration to low concentration with the help of proteins through a process called facilitated diffusion. Proteins act as channels or carriers to assist the movement of molecules across the cell membrane, allowing them to passively diffuse down their concentration gradient.
