Q1. A bioactive molecule, __________, that is used as an immunosuppressive agent in organ-transplant patients, is produced by a fungus.
A streptokinase
B statins
C cyclosporin A Correct
D lactic acid
Explanation
Cyclosporin A is a bioactive molecule produced by the fungus Trichoderma polysporum and is used as an immunosuppressive agent in organ-transplant patients. It helps reduce rejection of the transplanted organ by suppressing immune response. Streptokinase is produced by Streptococcus and is used as a clot-buster, not for transplant immunosuppression. Statins are cholesterol-lowering agents produced by yeast, mainly linked with inhibition of cholesterol synthesis. Lactic acid is produced by lactic acid bacteria during fermentation and has no role as the stated immunosuppressive transplant drug.
