True or False. The catalase test is a qualitative and selective assay.

Question

BlackTom AI · Accepted Answer

The question asks to evaluate the statement about the catalase test.
Option 1: 'True' — The claim that the catalase test is a qualitative and selective assay. While the catalase test is indeed qualitative, detecting bubbles as a readout of catalase activity, it is not selective. It does not select for organisms or preferentially isolate them; it simply indicates the presence or absence of the catalase enzyme in a given organism. Therefore labeling it as selective is inaccurate, making this option incorrect.
Option 2: 'False' — This option correctly identifies the inaccuracy in the statement. The catalase test is qualitative (it yields a positive or negative result based on bubble production) but it is not selective (it does not favor or distinguish among organisms in a selective way). The misunderstanding lies in combining qualitative with selective, which does not reflect how the test functions in practice. Hence, this choice is correct in indicating that the original statement is false.
In summary, the core idea is that the catalase test provides a qualitative result regarding enzyme presence, but it does not act as a selective assay, so the assertion as a whole is incorrect.
