A biosensor that uses both enzyme detection and an ion-specific electrode could be examining:

Question

Quizplus · Accepted Answer

The use of urease enzyme in combination with an ion-specific electrode can detect the production of ammonium ions. This is a common method for urea detection in biosensors. Glucose oxidase and cholesterol oxidase do not produce ions that can be detected by an ion-specific electrode. Bilirubin oxidase may produce hydrogen ions, but it is not a viable option for biosensor detection due to limitations in the practicality of this measurement. Therefore, choice A is the best option.
