BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzyme structures unfold (denature) when heated or exposed to chemical denaturants and this disruption to the structure typically causes a loss of activity. Protein folding is key to whether a globular protein or a membrane protein can do its job correctly. It must be folded into the right shape to function.

Detailed explanation-2: -Factors affecting enzyme activity 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-3: -Answer and Explanation: Introducing heat and/or chemicals that alter the enzyme’s pH are the two main environmental factors that cause enzyme denaturation.

Detailed explanation-4: -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-5: -When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.
