Question

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?

Answer 1

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).

Answer 2

Answer:

The result of this experiment is an example of competitive inhibition

Explanation:

Competitive inhibition It is a reduction in the rate of the reaction catalyzed by enzymes due to the presence of substances called inhibitors. Competitive inhibition occurs when the inhibitor molecules are similar to the substrate molecules and bind to the active center of the enzyme, preventing normal enzymatic activity. Competitive inhibition can be resolved by increasing the concentration of the substrate.
