What are receptors?
Understand the Problem
The question is asking for a definition and explanation of receptors in a biological or physiological context, potentially addressing their function and types.
Answer
Receptors are proteins that bind specific substances to trigger cellular responses.
Receptors are protein molecules located either on the surface or inside cells. They bind to specific substances (ligands) and initiate a cellular response.

More Information
Receptors play crucial roles in various physiological processes by detecting and responding to chemical signals. They are essential for cell communication and can be found in diverse locations such as cell membranes or within cells. They are involved in immune responses, sensory perception, and hormonal signaling.
Tips
A common mistake is to assume receptors only exist on the cell surface. They can also be internal, affecting how cells respond to their environment.
