Maltase is an enzyme that breaks down the disaccharide maltose into glucose molecules. The reaction usually takes place at a pH between 6 and 7. Which of the following best describes what would happen if the pH were decreased to 3? A) Maltase would not be able to function outside of its optimal pH range. B) Maltase would react with glucose molecules to form a new disaccharide. C) Maltose would break down into twice as many glucose molecules. D) Maltose would break down into monosaccharides other than glucose.
I think the correct answer from the choices listed above is option A. If the reaction of maltase is optimum at the pH range of 6 to 7, then most likely when the ph is decreased into three maltase would not be able to function outside of its optimal pH range. Hope this answers the question.
