Enzyme
Enzymes carry out almost all of the thousands of chemical reactions that take place in cells. They also assist with the formation of new molecules by reading the genetic information stored in DNA.\
Messenger
Messenger proteins, such as some types of hormones, transmit signals to coordinate biological processes between different cells, tissues, and organs.
Structural component
These proteins provide structure and support for cells. On a larger scale, they also allow the body to move.
Transport/storage
These proteins bind and carry atoms and small molecules within cells and throughout the body.
