Concept 3: Membrane Surface Receptors

Membranes have surface receptors that recognize signaling molecules such as peptide hormones. Binding of the signal activates other proteins to cause specific responses inside the cell, a process called signal transduction.

One of the common types of signal transduction is mediated by a class of proteins called G-proteins.
