You coat a Petri dish with fibronectin and proteoglycans and culture cells on the dish. The cells adhere to the dish. You repeat the experiment but this time add RGD tripeptides to the culture dish as the cells are added. The result of this experiment is an example of what biochemical process?

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).

I think the 4th is the right answer.

I'm sorry if I'm wrong.
