Metabolism

Think of metabolism as a mega workshop in our bodies, with countless workers buzzing around. There are two main teams in this workshop: Anabolic (builders) and Catabolic (destroyers).

Anabolic reactions (the builders) 🏗

  • What do they do? They build! Transform smaller molecules into bigger ones.

  • Energy requirement? Yes, they need energy. Imagine it like buying bricks to build a house.

  • Light up example

    • 🌱 Photosynthesis 🌞: Plants take small molecules like carbon dioxide and water, then use sunlight as their energy to create a big molecule - glucose!

  • How do they work?

    • Use energy mainly from ATP.

    • They're like chefs – when they cook, they produce water as a side dish! That's why they're called condensation reactions.

  • Real-life examples

    • Protein synthesis by ribosomes: Imagine ribosomes as mini-factories, building proteins piece by piece.

    • DNA replication: Think of it as a photocopier for our genetic material.

    • Synthesis of complex carbs: It's like turning single sugar cubes into massive sugar sculptures! Examples are starch, cellulose, and glycogen.
