When an enzyme’s active site changes its shape. This stops it from working.
|
|
|
When an enzyme’s active site changes its shape. This makes the enzyme work faster.
|
|
|
None of the above
|
Detailed explanation-1: -This is called denaturing and it means that the active site is no longer a complementary shape to the substrate molecule. The substrate molecule can no longer bind to the active site and enzyme-controlled reactions can no longer occur, therefore decreasing the rate of reaction.
Detailed explanation-2: -The shape of its active site changes following which the substrate does not fit into the enzymes anymore. Subsequently, the rate of reaction is influenced causing it to either slow down or stop.
Detailed explanation-3: -Enzyme denaturation happens when the structure of a protein and its functional group undergo conformational changes, resulting in inactivity. Denatured proteins have a looser, more random structure, and the majority of them are insoluble.
