Question

Enzymes that do not perform physiological functions are called as _________

(a) biosensor

(b) isoenzymes

(c) non-functional enzymes

(d) functional enzymes

I got this question during a job interview.

Enquiry is from Clinical Significance of Amylase, Transaminase and Proteinases in section Clinical Enzymology of Enzyme Technology

Answer 1

The correct option is (c) non-functional enzymes

To explain I would say: Enzymes that are present in low concentrations in plasma and have no physiological functions are called as non-functional enzymes. Whereas, enzymes that perform physiological function are termed as functional enzymes. Multiple forms of the same enzyme are referred to as isoenzyme. The analytical device which converts a biological response into an electrical signal is referred to as a biosensor.
