A body of knowledge and a process of gaining that knowledge
Answer:
Catalysis
Explanation:
Pepsin is able to break peptide bonds, turning large protein molecules into small peptide chains.
When pepsin acts to break down pepsinogen (inactive form of pepsin), it is accelerating pepsinogen → pepsin reactions, acting as a catalyst, reducing activation energy and favoring proteolytic reactions at a higher rate.
This process of accelerating reactions is characteristic of enzymes and is known as catalysis.
