Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When an enzyme denatures it means it can ____
A
function properly
B
no longer function
C
be okay
D
need oxygen
Explanation: 

Detailed explanation-1: -Enzymes are proteins, which in turn are chains of amino acids linked by ends. 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-2: -As with increases in temperature, extreme acidity or basicity can interrupt the molecular bonds holding an enzyme together. The loss of these intra-and inter-molecular interactions causes enzymes to lose their shape, resulting in denatured enzymes that are no longer functional.

Detailed explanation-3: -Enzymes work consistently until they are dissolved, or become denatured. When enzymes denature, they are no longer active and cannot function.

Detailed explanation-4: -Enzymes denature when they are put into conditions that are too far outside of their ideal temperature or pH range. BiologyEnzymes.
