BIOMOLECULES AND ENZYMES

Detailed explanation-1: -However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.

Detailed explanation-2: -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-3: -Changes in pH can cause an enzyme to denature (lose their precise shape) and the substrate won’t fit into the active site. Once an enzyme has denatured, it will not function again. The pH at which enzyme activity is highest is known as the optimum pH. Every enzyme will have its own optimum pH.

Detailed explanation-4: -When an enzyme denatures, its active site changes its shape, as you can see in this diagram. This is because the protein structure of the enzyme has changed. You might notice that the active site is no longer a complementary shape to a specific substrate molecule.

Detailed explanation-5: -Note 2: Denaturation can occur when proteins and nucleic acids are subjected to elevated temperature or to extremes of pH, or to nonphysiological concentrations of salt, organic solvents, urea, or other chemical agents. Note 3: An enzyme loses its ability to alter or speed up a chemical reaction when it is denaturized.
