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.
Answer:
Periods
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
That state of matter is known as liquid.
