What else can I help you with?
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
Which part of a cell allows substances to pass through it?
The cell membrane, specifically its lipid bilayer, regulates the passage of substances into and out of the cell through a process called selective permeability. Various proteins embedded in the membrane also assist in facilitating the movement of specific molecules across the membrane.
What is a semipermeable mebrane?
The cell membrane is called as semi-permeable membrane because it allows only certain/selective molecules to pass through it.It mostly allows only solvent molecules to pass.It is sometimes also called as selectively permeable membrane.
Why doesn't powder charcoal filter through a membrane?
Powdered charcoal particles are too large to pass through the pores of a membrane due to their size. The membrane acts as a barrier that only allows smaller molecules or particles to pass through, thus retaining the charcoal particles on one side of the membrane.
What is the term used for a layer that allows only certain molecules to pass through the cell membrane?
permiable
A membrane that allows only certain substances to pass through is a?
A permeable membrane
What part of the cell membrane allows small molecules to pass through?
the cell membrane
What is meant by membrane is membrane?
a partially permeable membrane allows some molecules or ions to pass through it
Why can't ions pass through the cell membrane?
Ions cannot pass through the cell membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through. Ions have an electric charge that makes it difficult for them to pass through the hydrophobic interior of the membrane.
What do you call a cell membrane that allows certain molecules to pass through?
A selectively permeable membrane.
A membrane that allows some but not all materials to pass through it is called .?
This sort of membrane is said to be semipermeable.
What kind of permeablilty is it when a membrane only allows some materials to pass?
yes, they only allow water moleclues to pass through the membrane.
What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
What do you call a membrane that only allows certain substances to pass through it?
semipermeable membrane
Definition of freely permeable membrane?
A freely permeable membrane allows all molecules or ions to pass through it without any hindrance. This means that there are no restrictions on the movement of substances across the membrane, and it is completely permeable to all solutes.
Using an example explain what is meant by a partially permeable membrane?
A partially permeable membrane is a barrier that allows only certain substances to pass through while blocking others based on their size or properties. For example, a cell membrane is partially permeable because it allows water and small molecules to pass through while blocking larger molecules like proteins.
Why can't charged molecules pass through the membrane?
Charged molecules cannot pass through the membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through based on their size and charge. The charged molecules are repelled by the hydrophobic interior of the membrane, which prevents them from crossing.
