What else can I help you with?
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
Diffusion of water molecules across a selectively permeable membrane?
it is osmosis
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
What involves the movement of solutes across a selectively permeable membrane by the process of difussion?
Osmosis involves the movement of solutes across a selectively permeable membrane by the process of diffusion. In osmosis, water molecules move across the membrane from an area of low solute concentration to an area of high solute concentration in order to equalize the concentration on both sides of the membrane.
The diffusion of water across a selectively permeable membrane through aquaporins is called?
osmosis
What is the net diffusion of water across a selectively permeable membrane?
Net diffusion of water across a selectively permeable membrane is known as osmosis. In osmosis, water moves from an area of high water concentration to an area of low water concentration in order to equalize the solute concentrations on both sides of the membrane.
What includes diffusion osmosis and facilitated diffusion?
These processes involve the movement of molecules across a semi-permeable membrane. Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Facilitated diffusion is the passive transport of molecules across a membrane with the help of specific proteins.
What are the differences between diffusion facilitated diffusion and osmosis?
Diffusion is the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion involves the use of transport proteins to move specific molecules across the cell membrane. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
The movement of water molecules across selectively premeable?
Osmosis movement of water from high concentration to low concentration.
What are the three forms of passive transport and how do they differ in their mechanisms of movement across the cell membrane?
The three forms of passive transport are diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion uses protein channels to help molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.
What is osmosis the diffusion of?
water
What is osmosis is restricted to the diffusion of this substance?
Osmosis is specifically the movement of water molecules across a selectively permeable membrane. It is not involved in the diffusion of other substances like ions or solutes.
