Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
After an enzyme is denatured, the substrate can ____ to the active site.
A
bind
B
no longer bind
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -This is because the protein structure of the enzyme has changed. You might notice that the active site is no longer a complementary shape to a specific substrate molecule. This means that the substrate cannot bind to the active site anymore. And this denatured enzyme can no longer catalyze enzyme-controlled reactions.

Detailed explanation-2: -Denaturation of enzymes causes bonds to be broken, structure to be disrupted and it stops functioning. This happens to enzymes when they are exposed to extreme, unsuitable conditions, for instance, high temperatures or extreme pH levels.

Detailed explanation-3: -This means that once the substrate has changed, it can no longer bind to the enzyme. The products are released and the enzyme is ready for another substrate molecule.
