Hello students.
00:01
Now in this question they have given that there's a microorganism in which there's this enzyme that is not present that is catalase.
00:10
Catalase enzyme is not present in this organism and they observe superoxide dismutase peroxidases enzymes.
00:19
So in this question they are asking if it is an obligate anaerope, obligate aerobe, facultative anaerope, aerotolerant anaerob or my micro aerophiles.
00:31
First, let us see one by one what each one can have.
00:35
Now, in case of obligate aerob, right, in case of the obligate aerob, the ones which can take in the oxygen, right, these have all three enzymes.
00:50
What do they have? they have catalase, superoxide dismutase and the peroxidases.
00:55
Along with that, if we see in case of the facultative anaerobes, right? in case of facultative anerobes, what you will observe? you will observe that there is only presence of catalase enzyme.
01:13
Okay.
01:14
So, one more thing if you see, in case of superoxide dismutase, one thing you will observe is that it is present in all organisms that can tolerate oxygen, even for the slightest bit, if they are able to tolerate the oxygen, then it will have the superoxide dismutase.
01:35
Okay...
