What type of diffusion is specific and passive and becomes saturated if all of protein carriers are in use?
Facilitated diffusion is the specific and passive type of diffusion that becomes saturated when all protein carriers are in use. This occurs because facilitated diffusion relies on specific protein carriers to transport molecules across the cell membrane, and once all carriers are engaged, the rate of diffusion cannot increase further.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
What is falicitated diffusion?
Facilitated diffusion is a type of passive transport where specific molecules are transported across the cell membrane with the help of transport proteins. Unlike simple diffusion, facilitated diffusion requires the presence of these proteins to facilitate the movement of molecules across the membrane.
What is non-specific facilitated diffusion?
Non-specific facilitated diffusion is a type of passive transport where molecules move across a cell membrane through specific protein channels without the need for energy. Unlike specific facilitated diffusion, which involves transport proteins that selectively allow certain molecules to pass, non-specific facilitated diffusion allows a broader range of molecules, such as ions and small polar substances, to diffuse through the membrane. This process relies on concentration gradients and helps maintain cellular homeostasis by enabling the movement of essential substances into and out of the cell.
How is facilitated diffusion similar to diffusion ion channels?
Facilitated diffusion and diffusion ion channels both involve the movement of substances down a concentration gradient without requiring energy input. However, facilitated diffusion involves the assistance of carrier proteins to transport specific molecules, while diffusion ion channels are specialized proteins that form pores in cell membranes for specific ions to pass through.

What incudes diffusion osmosis and facitated diffusion?
Diffusion is the movement of particles from an area of high concentration to low concentration. Osmosis is the specific type of diffusion where water molecules move through a selectively permeable membrane. Facilitated diffusion involves the movement of specific molecules across a membrane with the help of transport proteins.
Name three ways that culture can be spread Be specific?
Three ways that culture can be spread, including, Relocation diffusion, Expansion diffusion and stimulus diffusion.
What are the two types of possive transport?
The two types of passive transport are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across a cell membrane without the need for a specific protein. Facilitated diffusion, on the other hand, requires the assistance of specific transport proteins to move molecules across the membrane.
How does the bulk flow of filtrate into the capsule differ from diffusion?
The bulk flow of filtrate is a type of diffusion. Diffusion is a broad category of distribution of a substance within another substance. Diffusion can be specific or general in location and rate of flow.
What is faciillitated diffusion?
Facilitated diffusion is diffusion that occurs not through the cell membrane directly but through protein channels within the cell membrane. They are often, although not always, substrate specific.
How does Facilitated diffusion differs from diffusion in that facilitated diffusion?
Facilitated diffusion involves the use of carrier proteins to move specific molecules across the cell membrane, while simple diffusion does not require proteins and involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion is selective and allows for faster transport of specific molecules that may be too large or polar to diffuse freely through the membrane.
What specific substances can pass through a cell membrane by diffusion?
Oxygen

Does diffusion terminates at hearth?
Diffusion of molecules will not terminate at the hearth, as it is a continuous process that occurs until equilibrium is reached. However, the specific conditions at the hearth, such as temperature and molecular interactions, can affect the rate and extent of diffusion in that area.
Is osmosis the diffusion of small molecules?
Yes, osmosis is the diffusion of water molecules across a semi-permeable membrane. It is a specific type of diffusion that involves the movement of water from an area of higher concentration to an area of lower concentration.
