Question: would lowering the ph of lactase solution affect the enzyme?
Answer: Optimal pH The pH scale, ranging from 0 to 14, is used to determine the extent to which a solution is acidic or basic. Solutions that register as a 7 are considered neutral. ... Deviations in pH outside of this range, particularly to the high basic levels of 10 to 12, can cause the lactase enzymes to become denatured.
