Answer: adaptive immune response
Explanation:
Autoimmune disorders are caused by different microoorganism and drug which manipulates the immune system in a way that immune system become unable to recognise between self antigen and foreign antigen. In that case immune system treats foreign antigen as self antigen which cause systemic or organ specific damage.
The exact cause of autoimmune disorders is unknown and hence it is  thought that it is caused by adaptive immune response which builds against self antigens and causes damage to the cells.
Hence, some autoimmune disorders are thought to be caused by adaptive immune response.
 
        
             
        
        
        
Enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.
