Study Notes
Cell Signaling Components
- Three main components involved in cell signaling: receptors, signal transduction pathways, and effectors
- Receptors: recognize and respond to signals, located on cell surface or within cells
- Signal transduction pathways: series of molecular changes that transmit signal from receptor to effector
- Effectors: carry out response to signal, can be enzymes, ion channels, or transcription factors
Physical Cues in Cell Signaling
- Physical cues in cell signaling include: touch, vibration, light, temperature, and voltage
Chemical Signals in Cell Signaling
- Chemical signals in cell signaling mostly composed of: neurotransmitters, hormones, and growth factors
- Most hormones belong to the class of: proteins or steroids
- Peptides in cell signaling usually characterized as: short chains of amino acids
