Most enzymes do in fact work on a single substrate in most cases, this is because of the enzyme - substrate specificity. Certain reactant molecules acting as substrates can only fit in the "lock" of particular enzymes and undergo a conformational change and result in Unique products to be released after the reaction has occurred.
Answer: Fighting infection
Explanation:
Lymphatic system is a type of circulatory system in all vertebrates. It is a network of tissues ,blood vessels, and organs. The primary function of the lymphatic system is to control the fluid balance by collecting the fluid present in excess from the tissues and depositing them in the stream of blood. The secondary function of the lymph system is the production of lymphocytes (white blood cells) which fights against the disease causing pathogens. Hence, fights against infection.
Answer:
c. cysteine
Explanation:
Cysteine is a non essential amino acid. It contains sulfur in form of thiol group. A disulfide bond or bridge is formed between two thiol groups. It is represented as S-S. It is formed by oxidation of two cysteine molecules. The resultant disulfide bond is called as cystine which connects two polypeptide chains.
Cysteine is the only amino acid capable of forming disulfide bridge. It stabilizes protein's globular structure and plays an important role in protein folding and stability. Cysteine is required for protein synthesis, metabolic processes and detoxification. It is the part of beta-keratin which is the main protein in nails, hair and skin. If cysteine is mutated, formation of disulfide bond will be affected.
Aminos acids are used to build proteins
