Activity of various enzymes at various temperatures (a) and at various pH (b).
-Which temperature and pH profile curves on the graphs were most likely generated from analysis of an enzyme from a human stomach where conditions are strongly acid?

Question

Quizplus · Accepted Answer

The enzyme from a human stomach is most likely to have a pH optimum in the acidic range (pH 1-2) and a temperature optimum around 37°C (body temperature). Curves 1 and 4 show these characteristics, with a pH optimum around 2 and a temperature optimum around 37°C.
