Cell surface receptors of chemical messages are made of

Question

Quizplus · Accepted Answer

Cell surface receptors are made up of proteins. These proteins are specific to certain chemical messengers and bind to them to initiate cellular responses. The structure and configuration of the protein determine their specificity for particular chemical signals. DNA makes up the genetic material of the cell and is not directly involved in cell signaling. Lipids and sugars may be involved in signaling and cell communication, but they do not make up the receptor proteins themselves.
