Question

Describe 3 functions of the proteins found in the cell membrane.

Answer 1

Receptor proteins receive and transmit messages from outside to inside of the cell.

Integral proteins may function as pores and ion channels (passive transport), carriers and pumps (active transport), enzymes, and as receptors and transducers for chemical signals.

Enzymes catalyze chemical reactions.

Cellular adhesion molecules allow for cells to stick together.

Cell surface proteins form self, meaning that they can detect non-self cell surfaces that may be a threat, such as infections.
