The distortion (change in shape) of enzyme molecules which occurs at very high temperatures is known as
|
|
synthesis
|
|
|
specificity
|
|
|
replication
|
|
|
denaturation
|
Explanation:
Detailed explanation-1: -Enzymes can denature (change shape) when the temperature gets too high. Enzymes can only be used once in a chemical reaction. Enzymes can denature when the pH changes. Enzymes speed up chemical reactions.
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: -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.
