what is cell diffusion? It is a type of passive cell transport
In diffusion molecules move from a region of _____ concentration to a region of _____ concentration in order to decrease the concentration gradient from a region of high concentration to an area of low concentration
Is the diffusion from an area of low concentration to a region of high concentration energetically favorable? NO, it is not energetically favorable
what is concentration gradient? It is the difference between concentration in a space
Facilitated diffusion is also called ________ mediated diffusion
what is facilitated diffusion? it is the movement of molecules across the cell membrane through special transport proteins that are embedded within the cellular membrane
which kind of molecules are transported through facilitated diffusion? Molecules that are too large to fit through membrane pores
How do molecules get transported through facilitated diffusion? The molecules bind to specific protein carriers to form a complex which is then bind to a receptor site and move through the cellular membrane
In facilitated diffusion solutes move ______ the concentration gradient down the concentration gradient
