Effect Of pH Flashcards
1
Q
All enzymes have an…
A
Optimum pH value
2
Q
pH measures the…
A
Concentration of H+ ions in a solution
3
Q
If the concentration of hydrogen ions varies too much this changes the…
A
Charge on the molecule and breaks these bonds
4
Q
If the bonds break…
A
The tertiary structure of the enzyme changes
The active site is no longer the right shape for the substrate to fit into
The enzyme is denatured
5
Q
In the formation of an ESC the charge on the active site must match…
A
Those of the substrate
E.g. If the active site has too many H+ ions, the active site and the substrate may both have the same charge and the enzyme will repel the substrate
