6 Functions of Membrane Proteins:
1. Anchors
2. Identifiers
3. Enzymes
4. Receptors
5. Carriers
6. Channels
A. Leak Channels
B. Gate Channels
I only know of four, but here it goes:
- a binding site
- channels for passive transport
- pump for active transport
- as identity markers, recognizing other cells
i know all 6. --> 1. transport 2. enzymatic activity 3. signal transduction 4. cell to cell recognition 5. intercellular attachment 6. anchoring to cytoskeleton.

∙ 13y agoThe cellular plasma membrane does not simply form a "sack" in which to keep all the cytoplasm and other cellular organelles. The plasma membrane is a very important structure which functions to serve as a boundary between the cell and its environment and it is involved in the absorption and secretion of materials. It is selectively permeable allowing only small molecules to pass through and other substances like ions can be transported across the membrane by active transport.
The protein molecules in the plasma membrane also vary in function. They provide structural support and contain channels allowing transport of small molecules through the membrane. They also act as carriers which actively 'pump' molecules across the membrane and act as receptors for hormones arriving at the outer surface of the membrane. The proteins can serves as enzymes catalysing biochemical reactions in and on the membrane and can also serve as antigenic markers which identify the cell's blood or tissue type.

Many functions of the plasma membrane are carried out by?
Most of the active functions of plasma membranes are carried out by proteins.
Functions of plasma memberane?
Plasma membrane permits the entry and exit of some materials in the cells. Therefore, the plasma membrane is called a selective permeable membrane. Functions of plasma membrane : 1) Diffusion 2) Osmosis 3) Mediated transport
What determines the specific functions of the plasma membrane?
The relative amounts of proteins and lipids
What is the function of the cell membrane and the plasma membrane?
Cell membrane is also known as plasma membrane. Controls exchange of materials such as nutrients and waste between cells and their environment. Has other important functions for example to enable cells to receive hormones.
Four functions of the plasma membrane?
Four functions of the plasma membrane are:1) Serves as a gateway between the fluid inside and outside the cell. 2) Serves as a communicative device ( for molecules to bind to receptor proteins) 3) Identifies a cell coming from a particular individual. 4) Keeps the cell whole and intact.

How does nutrients enter a cell?
The plasma membrane.
Compare and contrast the functions of a cell wall to the functions of a plasma membrane?
The differences between cell wall and cell membrane are:Cell wall is made of cellulose while plasma membrane is made of lipids & proteins.Cell wall is freely permeable but cell membrane is selectively permeable.Cell wall is dead but plasma membrane is living.Cell wall is rigid but plasma membrane is smooth, elastic and flexible.Cell wall is found only in plant cells but plasma membrane is found in all liviing cells.
How do structures within cell allow the cell to be specialized?
The structures allow the cell to perform specific functions.
What is a steroid that functions as part of the plasma membrane and as a precursor for all other steroids in the body?
Cholesterol.
Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
What does plasma membranes do?
Plasma membrane functions to hold the contents of a cell together and separates them from the external environment.Plasma membrane also selectively controls the movement of substances going in or out of the cytoplasm, both actively and passively.
