What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
How are diffusion and facilitated diffusion diffrent?
Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.
Does osmosis or facilitated diffusion require the presence of membrane channels?
Facilitated diffusion requires the presence of membrane channels or transporters to move molecules across the membrane. Osmosis, on the other hand, does not require membrane channels as it involves the passive movement of water molecules through the lipid bilayer of the membrane.
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
How do most molecules cross the cell membrane?
Most molecules cross the cell membrane through passive diffusion, facilitated diffusion, or active transport. Passive diffusion relies on the concentration gradient, facilitated diffusion involves the use of protein channels or carriers, and active transport requires energy to move molecules against their concentration gradient.
What term refers to diffusion of water molecules through a selectively preamble membrane?
Osmosis is the diffusion of water molecules through a semi-permeable membrane to equalise osmotic pressure.
The rate of diffusion through a semipermeable membrane will be lowest when?
The rate of diffusion through a semipermeable membrane will be lowest when the concentration gradient between the two sides of the membrane is smallest, or when the thickness of the membrane is largest, limiting the movement of molecules.

Facilitated diffusion moves molecules through cell membranes passively.

Diffusion directly passes through the cell membrane unaffected by the hydrophobic part of the membrane. Facilitated diffusion uses proteins to assist in the movement of molecules. Ions have trouble moving through the hydrophobic part of the membrane.
What term describes the diffusion of the water through a semipermeable membrane down a concentration gradient?
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane
Where in the membrane does facilitated diffusion occur?
Diffusion will most likely to occur where there is a high concentration of gas or water then the particles distibute evenly to the area of low concentration. for example if you could smell a turkey cooking in the oven from upstairs without anyone telling you.
What are three ways molecules move through a semipermeable membrane?
Three ways molecules move through a semipermeable membrane are simple diffusion, facilitated diffusion, and active transport. In simple diffusion, molecules move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the movement of molecules across the membrane with the help of protein channels or carriers. Active transport requires energy and moves molecules against their concentration gradient.
Which term refers to the movement of water molecules through a selectively permable membrane?
diffusion
Function of the cell membrane of a cell?
The transport of molecules into and out of the cell through osmosis and diffusion
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called facilitated diffusion. In this process, carrier proteins aid in the movement of glucose across the membrane down its concentration gradient.
How do most molecules cross the cell membrane?
Most molecules cross the cell membrane through passive diffusion, facilitated diffusion, or active transport. Passive diffusion relies on the concentration gradient, facilitated diffusion involves the use of protein channels or carriers, and active transport requires energy to move molecules against their concentration gradient.
How can some substance diffuse through a cell membrane at faster rate than by diffusion alone?
In facilitated diffusion, there are temporary openings in the cell membrane that enable certain molecules to pass through quickly.
