Praxis II Biology

Answer: E, Properties of inhibitors include all of the above listed. Inhibitors are substances that decrease enzymatic activity.

Key Takeaway: Inhibitors function by binding to enzymes and preventing substrates from binding. Reversible inhibitors typically bind to the active site and can be displaced by substrate. Irreversible inhibitors bind to other sites on the enzyme can cause the enzyme to change shape so that substrate cannot bind. Reversible inhibitors do not undergo any conformational changes, whereas irreversible inhibitors are changed, much like substrates.
