This interesting question is from Drugs Biotransformation in section Biotransformation of Drugs of Drug Biotechnology

Answer 1

The correct choice is (c) In the cytoplasm in soluble form

Explanation: Non-microsomal enzymes include those that are present in soluble form in the cytoplasm and those attached to the mitochondria but not to the endoplasmic reticulum. These enzymes are non-specifically catalysing few oxidative reactions, the number of reductive reactions and hydrolytic reactions.
