Optimum pH Flashcards
1
Q
define an enzyme’s optimum pH
A
it means the pH value at which the enzyme works best
2
Q
What is particularly sensitive to pH?
A
The shape of the active site is particularly sensitive to pH
3
Q
What is each enzyme adapted to have at a specific pH?
A
There are adapted to have the correct shape at a partcicular pH value
4
Q
What is the optimum pH for pepsin and for most enzymes?
A
Pepsin=pH 2
most enzymes= 6-8 pH
5
Q
What happens if the pH is unsuitable?
A
The enzyme changes shape and the active site will no longer accept a substrate molecule.
6
Q
What are enzymes said to have at specific pH values?
A
Said to have their optimum activity at specific pH values
