The substance produced by a cell in a viral infection that can protect other cells from further infection are:
a. serotonin
b. colostrum
c. interferon
d. histamine
The answer is the option (c) interferon
Explanation: Interferon is a protein that prevents a healthy cell from being infected by a virus.
Serotonin: This is a neurotransmitter involved in mood regulation and not related to viral defense.
Colostrum: This is the first type of milk produced by mammals post-delivery and contains antibodies, but it doesn’t protect other cells from infections.
Histamine: This compound is involved in allergic reactions and inflammation but does not defend cells from viral attacks.
