Select one:
a. It is essential for the Kreb's cycle
b. It is essential for oxidative phosphorylation
c. It breaks down the more lethal superoxide radical

Coagulase test: A major difference between the Tube Test and the Slide Test, is that the Tube Test:
Select one:
a. Detects free or bound coagulase
b. Works only in rabbits
Explanation / Answer
Ans: (b)
b. The presence of catalase
Note:
In catalase test, we check whether an organism produces the catalase enzyme which is inferred by observing presence of bubbles.
