A biologist working in a lab adds a compound to a solution that contains an enzyme and substrate. This particular compound binds reversibly to the enzyme at the active site. Once the compound is bound to the enzyme, the catalysis of substrate to product stops. Which of the statements is true of the compound?

The effects of the compound is can be overcome by adding more substrate.

Explanation:

The compound is most likely to be an inhibitor since when it is added to the solution that contains an enzyme and a substrate it stops the catalysis of substrate to product.

Since it binds to the active site of the enzyme it is a competitive inhibitor.

The inhibitor cannot be an allosteric inhibitor because allosteric inhibitors bind permanently to the active site of the enzyme changing the conformation of the protein and the effect is irreversible. However, the compound binds reversibly to the active site of the enzyme.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.
