BIOMOLECULES AND ENZYMES

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.

Detailed explanation-2: -Denaturation is caused by the breaking of the bonds that hold the enzyme together in its three-dimensional shape. Heat can break hydrogen and ionic bonds, which disrupts the shape of the enzyme and will change the shape of the active site.

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.

Detailed explanation-4: -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-5: -Because enzymes are proteins, they are denatured by heat. Therefore, at higher temperatures (over about 55°C in the graph below) there is a rapid loss of activity as the protein suffers irreversible denaturation.
