Understanding the function of proteins like-Antitrypsin is crucial for developing effective treatments.
Emphysema is a chronic lung condition often caused by a deficiency of α-1 antitrypsin (AAT), a protein produced in the liver that protects lung tissue from damage by enzymes like neutrophil elastase.
(A) refers to a hormone, but α-1 antitrypsin is a protein, not a hormone.
(B) α-Interferon is used for viral infections and certain cancers, not emphysema.
(D) α-Lactalbumin is a milk protein and not related to emphysema treatment.
Thus, the correct treatment for emphysema caused by AAT deficiency is human α-1 antitrypsin protein (option C), which is administered as augmentation therapy.
Emphysema is a chronic respiratory disease characterized by the destruction of alveolar walls , leading to reduced lung elasticity. A major cause of emphysema is α-Antitrypsin deficiency , which results in unchecked activity of proteolytic enzymes like elastase. Elastase breaks down elastic fibers in the lungs, causing structural damage.
To treat emphysema caused by α-Antitrypsin deficiency, replacement therapy is used. This involves administering purified human α-Antitrypsin protein derived from blood plasma. The enzyme inhibits elastase and restores balance in the lungs.

The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
Charges are uniformly spread on the surface of a conducting sphere. The electric field from the center of the sphere in a point outside the sphere varies with distance \( r \) from the center as
