Answer: 2) Secretion of epinephrine and norepinephrine
Explanation: The Adrenal Medulla is part of the sympathetic nervous system and produces the hormones epinephrine (adrenaline) and norepinephrine (noradrenaline) in response to stress or danger. These hormones are crucial for the fight-or-flight response, which prepares the body for immediate action by increasing heart rate, blood pressure, and diverting blood flow to the muscles and brain.

Endopeptidases, also known as endoproteinases, are enzymes that hydrolyze peptide bonds within the polypeptide chain, breaking down proteins into smaller peptides. Examples include pepsin, trypsin, and chymotrypsin. In contrast, exopeptidases, or exoproteinases, cleave peptide bonds at the ends of the polypeptide chain, either at the N-terminal (aminopeptidases) or C-terminal (carboxypeptidases). These enzymes are involved in the final steps of protein digestion and the degradation of small peptides into individual amino acids.
