What moves materials in a cell membrane without using energy?
Passive transport processes like diffusion and facilitated diffusion move materials across the cell membrane without requiring energy. Diffusion occurs when molecules move from areas of high concentration to low concentration, while facilitated diffusion involves the help of protein channels to facilitate the movement of specific molecules.
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.
What is the name of the process of diffusion through a cell membrane?
The process is called passive diffusion, where molecules move from an area of higher concentration to an area of lower concentration across the cell membrane.
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
What Small droplets of liquid can pass through a cell membrane by the process of?
One method of movement across the membrane is by diffusion, which is related to osmosis.
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
What is the process that utilizes a carrier to move marerials across the plasma membrane in the direction of the concentration?
Diffusion is what carries materials across the plasma membrane. The diffusion cannot be moved across water.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
The process that utilizes a transporter to move materials across the plasma membrane against the concertration gradient using ATP?
diffusion
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion

What is the process of forcing materials across a membrane?
Osmosis.
Is diffusion of molecules across the cell membrane the most complex type of active?
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
What happens during the process of faciltated diffusion?
An Integral Membrane Protein Assists A Specific Substances Across The Membrane.
What is the name of the process of diffusion through a cell membrane?
The process is called passive diffusion, where molecules move from an area of higher concentration to an area of lower concentration across the cell membrane.
