Human Health and Diseases Question 81
81. Small proteins produced by vertebrate cells in response to viral infections inhibiting viral multiplication are known as
(a) Lipoproteins
(b) Immuglobulins
(c) Interferons
(d) Antitoxins
Show Answer
Answer : c
Hints & Solutions
(c) Lipoproteins are conjugated proteins having polypeptides in association with lipids. Immunoglobulins are the constituent of antibodies. Inteferons (INFs) are a group of three vertebrate glycoproteins (i.e. $\alpha, \beta, \gamma$, ) Out of these three $\alpha$ & $\beta$ are produced within virally infected cells. Interferon induces among adjacent cells, as antiviral state by inducing synthesis of the enzymes which inhibit the viral production cycle.
