What else can I help you with?
Is it active or passive transport or osmosis when particles move through protein doorways?
Since you are talking about the movement of particles, it would not be osmosis, because osmosis is the movement of water. Technically speaking, you could consider water a particle, but it is assumed that this question refers to movement of soluteparticles, and not solvent particles. Then, to determine if the movement is active or passive, one needs to know if energy is required and if the movement is up or down the concentration gradient. No energy requirement, it is passive. If a source of energy is needed, then it is active transport. Not sure what a protein doorway is. If you mean a pore, then the movement may be passive, or even facilitated diffusion.
What term defines the movement of materials along concentration gradient through channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
What are the four methods of passive transport?
Diffusion: process of movement of a substance from high concentration to low concentrationOsmosis: the passive of the solvent through a semi-permeable membrane to equalize concentrationsFacilitated Diffusion: also known as carrier mediated passive transport; the movement of substances into cells via carrier proteinsFiltration: process in which water and substances in the blood are pushed through the pores of the glomerulus. The resulting fluid is known as filtration
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!

How does facilitated diffusion work?
Facilitated diffusion is a process where molecules move across a cell membrane with the help of transport proteins. These proteins create a channel or carrier to allow specific molecules to pass through the membrane. This movement is passive and follows the concentration gradient, meaning that molecules move from an area of high concentration to low concentration.
Is facilitated diffusion?
Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane
What term defines the movement of materials along concentration gradient through channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
Is osmosis active or passive?
Osmosis is a passive process, meaning it does not require energy input from the cell. It is the movement of water molecules through a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.

The cell membrane, also known as the plasma membrane, is responsible for regulating the movement of water and substances through processes like active transport and passive transport. It acts as a selectively permeable barrier, allowing certain molecules to pass through while blocking others.
What is a passive trasport?
Passive transport is the movement of molecules through cell membranes with out the use of energy by the cell

The resulting fluid is known as filtration
Is filtration a passive process?
Yes, filtration is generally considered a passive process. It involves the movement of fluids through a filter or porous medium driven by pressure differences or gravity, without the need for external energy input. This process relies on the physical separation of particles from the fluid, allowing only certain sizes or types of substances to pass through.
Does simple diffusion require a helper protein?
No, simple diffusion does not require a helper protein. It is the passive movement of molecules across a cell membrane from an area of higher concentration to an area of lower concentration, relying on the concentration gradient. This process occurs directly through the lipid bilayer of the membrane for small, nonpolar molecules like oxygen and carbon dioxide.
When molecule enters through the cell through protein pump is it classified as active or passive transport?
When a molecule enters the cell through a protein pump, it is classified as active transport. This process requires energy, typically in the form of ATP, to move molecules against their concentration gradient, from areas of lower concentration to higher concentration. In contrast, passive transport does not require energy and occurs along the concentration gradient.
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
