Match List-I (Antibody Structure Fragment) with List-II (Functional Property)List-IP. Fab regionQ. Fc regionR. Hinge regionList-II1. Mediates effector functions like complement activation and macrophage binding2. Contains the highly variable antigen-binding sites3. Provides structural flexibility between the functional arms.सूची-I (एंटीबॉडी संरचना खंड) का सूची-II (कार्यात्मक संपत्ति) के साथ मिलान करेंसूची-IP. Fab क्षेत्रQ. Fc क्षेत्रR. हिंज (Hinge) क्षेत्रसूची-II1. पूरक सक्रियण (complement activation) और मैक्रोफेज बाइंडिंग जैसे प्रभावकारक कार्यों की मध्यस्थता करता है2. अत्यधिक परिवर्तनशील एंटीजन-बाइंडिंग साइटें शामिल हैं3. कार्यात्मक भुजाओं के बीच संरचनात्मक लचीलापन (flexibility) प्रदान करता है।
Explanation:
The Fab (Fragment antigen-binding) region binds the antigen. The Fc (Fragment crystallizable) region interacts with cell receptors (effector function). The hinge region offers flexibility to the Y-shaped molecule.
Fab क्षेत्र एंटीजन को बांधता है। Fc क्षेत्र सेल रिसेप्टर्स के साथ इंटरैक्ट करता है। हिंज (hinge) क्षेत्र Y-आकार के अणु को लचीलापन प्रदान करता है।
