non-polar molecules like fatty acids and retinol are transported through facilitated diffusion
What else can I help you with?
What is the process by which substances are moved through the cell membrane by a carrier molecule?
facilitated diffusion or active transport
What substances would be moved across the cell membrane by diffusion?
Substances such as oxygen, carbon dioxide, and small non-polar molecules can move across the cell membrane by diffusion. This process occurs from an area of higher concentration to an area of lower concentration until equilibrium is reached.
During active transport substances move from regions of what?
in active transport, where do molecules always go
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
The primary mechanism for exchange of substances across the capillary wall is?
Diffusion
How do substances move in a cell?
By Diffusion and Osmosis.Diffusion is literally a "process of scattering" (diffus). The scattering process of diffusion arises from the fact that all particles are constantly moving in random directions. During diffusion, particles move by chance from a region where their concentration is high, to a region where their concentration is low.osmosis -is the net movement of water molecules across a semipermeable membrane from a region of a higher concentration to a region of lower concentration...
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
What is the Process by which oxygen is moved into a cell?
Diffusion..
What is the process by which carbon dioxide is moved out of the cell?
Diffusion.
When two substances mix without being shaken or stirred?
When two substances mix without being shaken or stirred, it is likely due to the process of diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, leading to the even distribution of the substances.
What moves substances into and out of the cell in facilitated diffusion?
coffee
How does concentration determine the diffusion of substances?
It's a secret
