Question

An enzyme known as lipase digests fats. An inhibitor of lipase is used as a weight-loss drug. This inhibitor binds in the active site of lipase. This inhibitor most likely resembles a(n) _____.

Answer 1

The correct answer is - a fat

Step-by-step explanation:

According to the enzyme-substrate reaction the substrate binds to the active site of the enzyme and makes the enzyme-substrate complex and product is obtained after the reaction.

So for lipase, the substrate is fat which is broken down into simpler form by lipase. So to inhibit the lipase activity the inhibitor should fit into the active site of the lipase enzyme. The inhibitor will fit only if the shape of the inhibitor resembles the substrate(fat) of lipase. So this inhibitor should likely to resemble as a fat.
