Answer:
The correct answer is - D) 1000x.
Explanation:
pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the
H+ concentration in acidity/basicity. The more H
+ ions found in solution, the more acidic the substance is as acids donate H
+ ions.
You can calculate the concentration of H
+ from the pH and the equation
p
H =
−
log
[
H

arrange again
[
H
+
] = 10

So for a pH of 8, we get [
H
+
] =
10
^−
8
For a pH of 5, we get [
H

]
=
10^

^−5 /10

8=

= 1000
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.
