Question

If the physical change accompanying the reaction is heat output, the biosensors are referred to as _________________

(a) potentiometric biosensors

(b) optical biosensors

(c) calorimetric biosensors

(d) amperometric biosensors

I got this question in examination.

The above asked question is from Biosensors in division Biosensors of Enzyme Technology

Answer 1

Right answer is (c) calorimetric biosensors

For explanation I would say: If the physical change accompanying the reaction is heat output, the biosensors are referred to as calorimetric biosensors. In potentiometric biosensors, changes in the distribution of charges causes an electrical potential to be produced. Optical biosensors are those in which light output during the reaction is the physical change. In amperometric biosensors, movement of electrons produced in a redox reaction is the physical reaction.
