when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.

How does facilitated diffusion occur through a protein channel?

Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.


What types of molecules can diffuse through the cell membrane without using a channel protein?

Small, non-polar molecules like oxygen, carbon dioxide, and water can diffuse through the cell membrane without the need for a channel protein. Their small size and non-polar nature allow them to passively pass through the lipid bilayer of the membrane.


Is a protein that forms an ion channel through a membrane is most likely to be a peripheral protein a trans membrane protein a phospholipid an enzyme or an entirely outside the phospholipid?

A protein that forms an ion channel through a membrane is most likely to be a transmembrane protein. Transmembrane proteins span the lipid bilayer, allowing them to create channels for ions to pass through the membrane. Peripheral proteins are typically found on the surface of the membrane and do not form channels.


How do large polar molecules enter the cell?

Large polar molecules enter the cell through facilitated diffusion or active transport, which require the assistance of specific protein channels or carriers in the cell membrane. These proteins help transport the molecules across the membrane against a concentration gradient or when the molecules are too large to pass through on their own.


What type of protein helps molecules not lipid soluble or too large pass through the cell membrane?

These proteins are attached to the membrane and their is a great variety of them. There one called the integral protein that crosses all the way through while others are triggered by biochemical reactions.These are also called carrior proteins and protein channels

Does osmosis move phospholipid bilayer or protein channel?

Osmosis moves water molecules across the phospholipid bilayer of a cell membrane. Protein channels help facilitate the movement of water and other molecules by providing a pathway through the membrane.

What is a school analogy for channel protein?

A school analogy for a channel protein is a hallway with a designated passageway. Just as a channel protein serves as a selectively permeable pathway for specific molecules across a cell membrane, the hallway provides a specific pathway for students to move through and reach their designated classrooms. Other types of molecules or students may be excluded from entering the pathway, ensuring only the intended molecules or students can pass through.
