Study Notes
Receptor Location and Function
- Cell surface receptors are a type of receptors located on the outer membrane of cells.
GABA Function
- GABA (Gamma-Aminobutyric Acid) inhibits the electrical activity of neurons, acting as an inhibitory neurotransmitter.
Receptor Classification
- Receptors can be classified based on their mechanism of action, binding site, and functional response, but NOT based on their molecular weight.
Receptor Composition
- Receptors are typically composed of proteins, often with specific binding sites for molecules such as neurotransmitters, hormones, or other signaling molecules.
Receptor Action
- Receptors receive and transduce signals, converting extracellular signals into intracellular responses, allowing cells to respond to changes in their environment.
