A hydrogen bond is a favorable interaction between an atom with a basic lone pair of electrons (a Lewis Base) and a hydrogen atom that has been partially stripped of its electrons because it is covalently bound to an electronegative atom. On the other hand, if the temperature lowers below the optimal temperature, the enzyme activity lowers until the enzyme reaches a minimum temperature at which the enzyme activity is the least. the higher the rate of the reaction, this is true until all enzymes are involved in a enzyme-substrate complex, or saturated with substrate. Thirteen of these genes provide instructions for making enzymes involved in oxidative phosphorylation.
