🚀 The Big Picture: Signalling molecules can have either localized effects (short distance) or distant effects (long distance) based on how far they are transported.

Localized effects of signalling molecules 🎯

  • Example: Neurotransmitters
  • How do they work? 🤔
    • Released by presynaptic neurons.
    • Travel a super-short distance (about 20 nanometres) to affect the one postsynaptic neuron.
  • Real-world example: 🌍
    • Think of a text message you send to your friend sitting right next to you. It's meant for them and them only!
