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 rate of catalysis of substrate to product is greatly reduced. Which of the statements are true of the compound?

Enzymes are biochemical catalysts that speed up chemical reactions. They act on specific substrate to convert them to products.
Compounds known as inhibitors slow down the rate of enzyme activity.
Inhibitors are classified as competitive and non-competitive inhibitors.
Competitive inhibitors will compete with the substrate to bind the active sites on the enzyme. The effect of competitive inhibitors may be reduced by increasing the concentration of the substrate.
The compound added by the biologist was a competitive inhibitor and therefore adding more substrate would overcome its effect on enzyme catalysis
Non-competitive inhibitors binds the active site of the enzyme permanently and prevents the substrate from accessing the active sites.
