|
If an enzyme becomes over heated what effect, if any, will the heat have on the enzymatic activity?
|
|
The enzyme will not store much chemical energy.
|
|
|
The enzyme will be denatured and cannot catalyze reactions.
|
|
|
The enzyme will lose its net electrical charge.
|
|
|
The enzyme will lose stored genetic information.

Explanation:
Detailed explanation-1: -Thus too much heat can cause the rate of an enzyme-catalyzed reaction to decrease because the enzyme or substrate becomes denatured and inactive.
Detailed explanation-2: -Enzymes are protein molecules that get denatured at high temperatures. High heat breaks hydrogen and ionic bonds leading to disruption in enzyme shape. The enzyme loses its activity and can no longer bind to the substrate.
Detailed explanation-3: -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.
