Final answer:
Chemical digestion is the area of chemistry being applied when studying the chemical reactions during food digestion in the stomach.
Step-by-step explanation:
The area of chemistry being applied when a scientist studies the chemical reactions that take place during the digestion of certain foods in our stomach is chemical digestion. Chemical digestion refers to the breakdown of large food molecules into smaller subunits by enzymes through hydrolysis. In the case of digestion, enzymes such as pepsin in the stomach are responsible for breaking down protein into smaller peptides and amino acids.
