What else can I help you with?
What are diffusions of particles through protein channels called?
Diffusion of particles through protein channels is called facilitated diffusion. This process allows specific molecules or ions to pass through the cell membrane with the help of transport proteins.
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins
How do proteins leave the cell?
Proteins leave the cell through a process called exocytosis, where they are packaged into vesicles and transported to the cell membrane. The vesicle then fuses with the cell membrane, releasing the proteins outside of the cell.
What moves particles like oxygen into cells?
Particles like oxygen are moved into cells through the process of diffusion. This is a passive process where particles move from an area of high concentration to an area of low concentration, crossing the cell membrane. Additionally, specialized proteins like transporters and channels can facilitate the movement of specific particles into cells.
How do polar molecules cross the cell membrane?
Polar molecules cross the cell membrane through a process called facilitated diffusion, where they move with the help of specific transport proteins embedded in the membrane. These proteins create channels or carriers that allow polar molecules to pass through the hydrophobic interior of the membrane.
What is the definition of active transport?
active transport is an energy reqiuring process in which transport proteins bind with particles and move them through a cell membrane
What is the process by which tiny particles can pass through the cell membrane?
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.

Proteins leave the cell through a process called exocytosis, where they are packaged into vesicles and transported to the cell membrane. The vesicle then fuses with the cell membrane, releasing the proteins outside of the cell.
Packaged proteins are removed from cells through the process of?
exocytosis. This process involves the fusion of vesicles containing the proteins with the cell membrane, allowing the proteins to be released outside of the cell.

Particles like oxygen are moved into cells through the process of diffusion. This is a passive process where particles move from an area of high concentration to an area of low concentration, crossing the cell membrane. Additionally, specialized proteins like transporters and channels can facilitate the movement of specific particles into cells.
What functions to membrane proteins have?
The plasma membrane proteins have many functions. They pass on information through the membrane, they give the cell structural support and recognize different particles within the cell, and they are also transporters.
What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
The process is called facilitated diffusion. It is a type of passive transport that involves the movement of molecules across a membrane with the help of specific proteins called carrier proteins or channel proteins. These proteins assist the molecules in crossing the membrane by providing a pathway.
How do polar molecules cross the cell membrane?
Polar molecules cross the cell membrane through a process called facilitated diffusion, where they move with the help of specific transport proteins embedded in the membrane. These proteins create channels or carriers that allow polar molecules to pass through the hydrophobic interior of the membrane.
Do you see particles moving from left to right through the membrane?
Yes, particles can move from left to right through a membrane, depending on several factors such as the concentration gradient, membrane permeability, and the presence of transport proteins. If the concentration of particles is higher on one side of the membrane, diffusion may drive them to move towards the area of lower concentration. Additionally, active transport mechanisms can also facilitate the movement of particles against their concentration gradient.
What roles do membrane proteins play in making the cell membrane selectively premable?
The proteinshave certain 'identifiers' attached to them, which only allow certain particles through, making it selectively permeable.
