It is a selectively permeable membrane that allows certain substances in and out, but keeps harmful substances from entering the cell. It could be compared to the security guard at the door of an airport that makes sure that nobody dangerous gets in or out.

What is aquaporins?
Aquaporins are protein molecules embedded in the phospholipid bilayer (cell membrane ) of some cells. They transport water across the cell membrane.
What are cell membrane pores are made of?
Cell membrane pores are made up of protein.
Why are pores in the cell membrane different sizes?
They selectively allow certain size molecules to enter, or not to enter, the cell.
What is the protein coating of Bacteriophage T2?
OmpF (outer membrane protein)
What are Different types of mechanics?
There are two main types of transport systems which are used to transport solutes across a cell membrane: passive transport and active transport. Passive transport is where a protein in the membrane simply provides a 'hole' in the membrane, which allows the solute to flow freely in both directions. In this case, the flow of the solute is determined entirely by the concentration gradient across the membrane, and no energy is input to aid the movement (hence the term passive). Active transport is where the protein in the membrane actually binds to the solute, and conformational changes in the protein shape literally carry the solute across the membrane, then release it on the other side. This mechanism is designed for situations where movement of solutes against their concentration gradient is required, and requires the input of energy. This energy can come from one of a few places: * Primary active transport involves deriving the energy required to move the solute from the hydrolysis of ATP (Adenosine Triphosphate). In this case, the protein acting as the carrier is referred to as an ATPAse. * Secondary active transport involves deriving the energy from the movement of another solute across the membrane. This second solute will be flowing in the direction of its concentration gradient, so energy is released as it crosses the membrane. This allows it to drive the conformational changes in the protein that carry the solute across.
What is pore protein?
integral protein that embedded to the plasma membrane. Allow small substances to cross the plasma membrane.
The plasma membrane is a thin sheet of lipid embedded with?
protein
What proteins are embedded in the plasma membrane?
They are called integral proteins
Whats the function of tethered protein?
A tethered protein is one that is not embedded inside a membrane but is suspended away from it.
What is a calcium ion receptor?
This is a protein on or embedded in a cell membrane that activates when a Calcium ion interacts with it.
Which cell part is a thin membrane that lets materials in and out of a cell?
Referred to as either a cell membrane or a plasma membrane. Is composed of a phospholipid bilayer with embedded protein channels.
What is a complex molecule that is embedded in the cell membrane that helpss move substances move into and out of a cell?
Transport protein

What is the function of protein channels?
Channel proteins take specific substances across cell membranes. Molecules passing through the membrane by channel protein is called mediated transport. To transport the substances, the channel protein must be embedded in the total cell membrane.
What are the two proteins found in the cell membrane?
The two main proteins found in the cell membrane are integral proteins and peripheral proteins. Integral proteins are embedded within the membrane and can span across it, while peripheral proteins are located on the surface of the membrane and are not embedded within it. Both types of proteins play important roles in various cellular functions including transport, communication, and cell signaling.
What membrane of a cell acts like a channel?
The cell membrane contains various proteins that act as ion channels, allowing specific ions to pass through. These membrane channels are integral in regulating the transport of ions and maintaining the functionality of the cell.
