📘 Class 11 Biology – Locomotion & Movement
🎯 Part 6 – Structure of Contractile Proteins
📍 NEET 2026 | NCERT Line By Line
Is video mein maine Thin Filament aur Thick Filament ka complete structural explanation detail mein cover kiya hai – bilkul NCERT ke according 🔥
🧬 Thin Filament (Actin Filament) Structure:
✔️ Two F-actin (Filamentous Actin) helically wound around each other
✔️ F-actin = Polymer of G-actin (Globular Actin is monomer)
✔️ Two Tropomyosin filaments present
✔️ Tropomyosin par regular interval par Troponin complex present
✔️ Troponin subunit par masking site (myosin binding block karta hai)
✔️ Resting site concept clearly explained
👉 Agar masking site covered hai toh Myosin Actin se attach nahi hoga — ye concept NEET ke liye bahut important hai ⚠️
💪 Thick Filament (Myosin Filament) Structure:
✔️ Myosin monomer structure
✔️ Meromyosin (Heavy & Light) explanation
✔️ Heavy Meromyosin (HMM) & Light Meromyosin (LMM)
✔️ Globular head, short arm & tail structure
✔️ Cross arms & Cross bridge formation
✔️ Head contains: • Active ATPase enzyme ⚡
• ATP binding site
• Actin binding site
📊 Last mein maine Actin & Myosin ke NCERT diagram ko line-by-line decode karke explain kiya hai + pura topic summary diya hai taaki revision strong ho 💯
🔥 Ye video help karega: • NEET 2026 aspirants
• Board exam students
• Concept clarity chahne wale serious students
• NCERT based preparation karne wale
