This intriguing question originated from Enzymes topic in portion Enzymes of Enzyme Technology

Answer 1

Correct answer is (c) isoenzyme

Explanation: Multiple forms of the same enzyme is referred to as isoenzyme. The enzymes having allosteric sites, other than catalytic site which is used for binding for regulatory metabolites is referred to as allosteric enzymes. Biosensor is an analytical device which converts a biological response into an electrical signal. Regulatory metabolites required for binding to allosteric sites are called effectors.
