Lock and Key Hypotheses
In this video, we explore the Lock and Key Hypothesis, the classic model proposed by Emil Fischer to explain how enzymes achieve their remarkable specificity. Students will learn what enzymes are, how they act as biological catalysts, and why cells depend on them to carry out essential reactions like photosynthesis, respiration, and protein ...

🧬 Enzyme Substrate = The Perfect Match! 💥 Just like a lock and key 🔑, an enzyme only works when the substrate perfectly fits its active site. That’s how reactions happen efficiently — no match, no reaction! If you’re studying IGCSE, IB, or A-Level Biology, remember: enzyme specificity is key to understanding biochemistry questions. 💡 | Biokatalyst
