Question

Enzymes are kinetically important for many of the complex reactions for plant and animal life to exist. However, only a time amount of any particular enzyme is required for these complex reactions to occur. Explain.

Answer 1

Enzymes are the biological catalyst, which accelerates the rate of any biological reactions. They are indispensable for facilitating any complex biological reaction within a particular time period, which is very important to sustain life. For example, orotidine 5’ decarboxylase catalyzes the formation uridine monophosphate from orotidine monophosphate, an important step of the pyrimidine biosynthesis within a millisecond. Without this particular enzyme, this reaction would take millions of years. Therefore, enzymes are kinetically very crucial to accomplish many complex biological reactions. Similar to the other chemical catalyst, enzymes are not consumed in the reaction and the equilibrium of the reaction remains unaltered. The specificity of an enzyme activity varies with the temperature and pH of the system as well as the presence of any activator or inhibitor in the system. During the reaction, substrate attachment to the enzyme’s active site alter its confirmation. Thus, this altered structure of the enzyme revert back to its original form after accomplishing the reaction without hampering its amount in the system. Therefore, a tiny amount of a particular enzyme is sufficient to carry out its specific reaction within a system.  Enzymes are the biological catalyst, which accelerates the rate of any biological reactions.
