Receptor

The video explains the role of cell surface receptors, which bind to specific signaling molecules or external stimuli to trigger responses. These receptors are crucial in various human body functions, such as sensory perception and immune response. Sensory receptors detect external signals like light and sound, while immune cell receptors respond to pathogens.
