Answer: Enzymes lower the activation energy found in food molecules
Explanation:
Food substances like yam, potatoes, egg etc are all made of chemical elements bounded to one another by chemical bonds such as hydrogen bonds, covalent bonds etc
During digestion, these bonds must be broken for carbohydrates to yield glucose, protein to yield amino acids.
Hence, added enzymes lowers the strength of this bonds i.e activation energy, by placing them into their active sites, which is equipped to cleave specific bonds
Thus, digestive reactions are quicker in the presence of enzymes than otherwise.
