What makes enzymes unique and efficient?

Answer 1

It's linked with zinc, so that is probably why it's efficient.

On the other hand saying it's unique is a biased opinion, you might think it's unique, while other people don't even care about enzymes.

Joncold4water's answer:

Enzymes are protein or RNA molecules that are unique because they are catalysts, meaning they accelerate the rate of a biochemical reaction in an organism so that reactants are converted to products at amazing speed (speed of an enzymatically-catalyzed reaction is called the "turnover time." or in other words. the number of moles of reactant consumed by the reaction per unit time) this high efficiency is frequently required in a living organism because needs for localized supplies of a given product can accumulate very quickly and the enzyme molecule has to be at the right place and at the right time. A good example would be the enzyme sarcoplasmic calcium-ATPase. the reaction this enzyme catalyzes is the removal of calcium ions from the interior space of a muscle cell so that relaxation of the muscle can occur. Muscles which can't relax eventually break down structurally because of the elevated metabolism resulting from sustained contraction without a relaxation phase. Enzymes are as efficient as they are because they will only catalyze a reaction for which they are structurally and dynamically suited. In catalyzing a chemical reaction the enzyme accelerates the speed of conversion of reactants to products by lowering the so-called "activation energy," (initial energy "hump") required to overcome before the rest of the reaction can proceed with the release of potential energy along the reaction coordinate or, in other words so that the chemical reaction can proceed spontaneously (i.e., without further input of energy into the system). This is accomplished by the enzyme's ability to slightly change the structural conformation of the reactant so that its potential energy is lowered and the ability for the enzyme in that state to bring the reactants into a more exact proximity of one another so that the reaction proceeds faster. Unlike products and reactants, enzymes are neither produced nor consumed by virtue of the job they do in accelerating the rate of the reaction they catalyze. Commercial, purified supplies of enzymes tend to be highly-labile and difficult to keep stable and active once reconstituted at the lab bench. As a rule. reconstituted enzymes are kept in wet ice and used as soon after reconstitution as possible. Enzyme activity is counted in units. a unit of the activity of any enzyme is the number of iterations of the reaction they catalyze that can been accomplished per unit time. The specific activity of an enzyme preparation is measured as the number of units of enzyme activity per unit weight of the enzyme preparation.
