What does the oxidase test determine?
A) If the bacteria have the enzyme, oxidase, to reduce oxygen to carbon dioxide
B) If the bacteria have oxidase, which will allow for the oxidation of carbohydrates
C) If the bacteria can hydrolyze urea to ammonia and carbon dioxide
D) The presence of the cytochrome oxidase system that oxidizes reduced cytochrome with molecular oxygen

Question

Quizplus · Accepted Answer

The oxidase test is used to determine the presence of the cytochrome oxidase system in bacteria, which is responsible for oxidizing reduced cytochrome with molecular oxygen. Option A and B are incorrect because the oxidase test is not related to the oxidation of carbohydrates or the reduction of oxygen to carbon dioxide. Option C is incorrect because it refers to the urease test, not the oxidase test.
