Biomembrane Structure and Function

• Paul D. Brown, PhD
• BC21D Bioenergetics Metabolism

Signal transduction

• Receptors are proteins associated with cells that
  recognizes neurotransmitters, hormones, and
  drugs.
• Signaling molecules transmit their information to
  cells in a variety of ways.

3
Signal transduction

• G-proteins cycling
• Aagonist
• Rreceptor

4
Signal transduction

• cAMP second messenger system

5
Signal transduction

• Phosphoinositol second messenger system

6
Signal transduction

• Guanylate cyclase cGMP and NO as second
  messengers

7
Signal transduction

• Signalling by acetylcholine
