Each enzyme is comprised of covalently linked amino acids...enzymes are proteins
Answer:
The results of the experiment is a process called competitive inhibition.
Explanation:
Competitive inhibition is a process where an inhibitor (RGD tripeptides in this case) that resembles a normal substrate bind the active site of an enzyme and prevents the a real substrate from binding and a product from being formed (blocking enzymes active site).
When RDG tripeptides are added the cells would not adhere to the dish (competitive inhibition).
