✓ Answer: D Proteins are not affected by temperature
The statement 'Proteins are not affected by temperature' is NOT true. Proteins are indeed affected by temperature. Heat can break hydrogen bonds and hydrophobic non-polar interactions. This occurs because heat increases kinetic energy, causing molecules to vibrate so rapidly and intensely that the bonds break. As a result, the proteins in eggs coagulate and denature during cooking.
