We would eventually parish because we need the nutritional benefits of the apple much sooner than the previous time frames. If our own enzymes are exposed to heat above their optimal functioning temperature, they become progressively less proficient. Hyperthermophiles must, therefore, produce enzymes that can tolerate extreme temperatures. This raises, however, another question. How do the bonds between atoms in extremozymes stay in tact under hot conditions.
Enzymes are very large protein molecules.
These molecules are constructed of many atoms all of which are bonded to each other in distinct patterns. Putting aside the actual complexity of these molecules, heat effects the strength of the bonds. At cool temperatures the wall would be strong and stable, and at high temperatures the wax would melt and the wall would crumble. Whether the subject is a whale or an extremophile, often the key of interest unlocks the door of importance. Even though a fair amount of uncertainty exists with fully understanding extremozymes, some have been found beneficial to humans.
