The three cellular components, which takes part in the process of metabolism and are affected by the modifications in temperature are ribosomes, cell membrane, and enzymes.
All these are formed of a certain type of protein, which can become denatured when exposed to high enough heat or stop gets functioning at too low temperature. The high temperature can disrupt the non-polar hydrophobic interactions and hydrogen bonds. This takes place as heat enhances the kinetic energy and makes the molecules to throb so briskly and viciously that the bonds get disordered.
