Answer : b
Hints & Solutions
(b) Microbial transformation is a biological process in which organic compounds are modified into reversible products. These biotransformation reactions are catalysed by purified enzymes present in microbial cells or pure cullures of micro-organisms. Cholesterol forms a major component of animal cell membranes liposomes (artificially created spheres surrounded by a phospholipid bilayer like a membrane). Cholesterol is used for microbial transformation (transgenics).
