A physician is attempting new therapies for HIV patients who are suffering from an impaired immune response. He decides to try using a recombinant form of colony-stimulating factor cytokine (CSF). Why?
A. CSF is a strong inducer of antiviral activities in our cells, and may help our immune system fight off the effects of HIV for a longer period of time.
B. CSF will hyperstimulate the activities of the macrophages, leading to ingestion and destruction of HIV-infected cells.
C.
CSF will help to stimulate the production of new lymphocytes-the very cells that are infected and depleted during an HIV infection. This may help to keep the patients' immune responses "normal" for a longer period of time before they succumb to full-blown AIDS.
D. CSF will drive up the production of lactoferrin, a strong antiviral compound produced in our mucus membrane secretions.

How does inhibition of an enzyme-catalyzed reaction by a competitive inhibitor differ from inhibition by a noncompetitive inhibitor?
A) Competitive inhibitors interfere with the enzyme; noncompetitive inhibitors interfere with the reactants. B) Competitive inhibitors bind to the enzyme reversibly; noncompetitive inhibitors bind to it irreversibly. C) Competitive inhibitors change the enzyme's tertiary structure; noncompetitive inhibitors cause polypeptide subunits to dissociate. D) Competitive inhibitors bind to the active site of the enzyme; noncompetitive inhibitors bind to a different site.
