Standard biological concept: zero enzyme activity at very high heat = protein denaturation.
Enzymes are proteins whose catalytic activity depends on a specific three-dimensional tertiary conformation. At extreme temperatures like $95^\circ\text{C}$, heat disrupts the non-covalent hydrogen and ionic bonds stabilizing this shape, ca...
