Membrane proteins can have a variety of functions. What functions can these proteins have? Check all that apply.
SpyIntel [72]

Answer;

-Channel, Recognition, reception, transport

Explanation;

Membrane proteins serve a number of functions:

• Channel proteins: allow dissolved molecules to diffuse through the membrane. Some of these proteins are structured in a way that allows only certain small molecules or ions through.

• Carrier proteins: These have binding sites that allows them to bind to certain substances and physically move the substance from one side of the membrane to the other.

• Receptor proteins: These proteins have active sites shaped to fit specific signal molecules, such as hormones. Once the protein is activated by the substance, it sets off a series of changes in the cell,such as increased metabolic rate or cell division.

• Recognition proteins: These proteins, called glycoproteins (glyco = sugar) have complex carbohydrates attached to them. These form the identification system that allows your body cells to recognize each other as self instead of foreign.

• Protein filaments: Long strands of protein on the inside surface of the membrane help support and strengthen the cell membrane, forming the cytoskeleton.
