Vesicles - tiny cellular bubbles 🔬

  • What Are They? Vesicles are small droplets of fluid, encased in a membrane. Imagine them like tiny bubbles floating around inside a cell.

  • Two Types

    • Inside the Cell: Common structures floating around.

    • Outside the Cell: Called exosomes.

  • Ancient Helpers: They might've been superstars during early cell evolution!

Phospholipids - the building blocks 💧

  • What's in the Name?
    • Hydrophilic Head: Loves water. Like a fish in the ocean! 🐟
    • Hydrophobic Tails: Afraid of water. Like a cat avoiding a bath! 🐱
    • Amphipathic: A fancy word when something has both hydrophilic and hydrophobic parts.
  • Their Role? When mixed with water, phospholipids create a bilayer. Imagine a sandwich with the hydrophilic heads as the bread facing outwards and the hydrophobic tails like the peanut butter facing inwards. Yum! 🥪
