My bio teacher gave us a hint that it’s related to the purpose of the stomach. I already know that it can’t function in an acidic environment, now I just need to explain why it can function in an alkaline (base) environment. Thanks!

pH 7-11 is a huge range. Because pH is log scale 11 is 10000x more basic than 7, which seems kind of unreasonable for the optimal range of an enzyme. That’s huge.
But catalase is found mostly in the liver. Liver cells have a pretty much neutral pH of 7. Blood is expected to have a pH of 7.4 which is slightly basic, so it makes sense that the range of catalase leans more towards neutral-basic than neutral-acidic
