BIEnzymes: The Superheroes of Biochemistry! ✨🔬
Enzymes are tiny but mighty organic molecules that act as catalysts, speeding up chemical reactions without being used up themselves.
🧩 How they work:
Substrate (reactant) fits into the enzyme → forming the enzyme–substrate complex.
Through the induced-fit model, the enzyme slightly changes shape to hug the substrate more closely.
End result? The substrate is converted into products, and the enzyme is free to work again! 🔁
⚡ Helpers (Co-factors):
Sometimes enzymes need extra assistance from vitamins (like B6, B12) or minerals (Zn²⁺, Cu²⁺, Mn²⁺) to function properly.
⛔ Inhibition:
Competitive: A “look-alike” molecule sneaks in and competes for the active site (blocking the real substrate).
Non-competitive: A molecule binds elsewhere on the enzyme, changing its shape and shutting it down.
🌡️ Factors affecting enzyme activity:
Temperature: Enzymes work best at ~37°C. Too cold = sluggish 🥶. Too hot = denatured and destroyed 🔥.
pH: Each enzyme has its sweet spot! For many, it’s around pH 7. Too acidic or too alkaline → structure falls apart.
💡 Example: Peroxidase enzyme breaks down hydrogen peroxide (H₂O₂). But if a competitive inhibitor like hydroxylamine shows up, it blocks the enzyme from working.
⚡ TL;DR: Enzymes = Life’s speed boosters. Without them, essential reactions in your body would be way too slow to keep you alive! ❤️
