Can life exist without enzymes?

The term life, is in itself, a vague entity. Different bend have different perceptions of what life is. To some, life is the quality of living; to others, it is their finespun existence itself. In biological terms, I have delimitate life to be the ability to function, be it as a complex multicellular beingness, or a single-celled protozoan. This is brought about by vital processes such as regulation and control, respiration, defence and reproduction. Without these processes, the organism cannot function. We must then analyse what role do enzymes whoremaster in these processes. An enzyme is a globular protein. Its basic unit is the aminic group acid, made up of the elements Carbon, Nitrogen and Hydrogen. Each enzyme has a particular(prenominal) 3-dimensional configuration, and an active localise specific to the molecule it binds to. The active direct is made up of a unique sequence of R groups, with different shapes, giving the site its shape. There, the subst assess b inds and undergoes a straight of catalytic reactions after which the products leave the active site. This leaves the enzyme free to maintain out more catalytic reactions. An enzyme is also sensitive to lurchs in temperature and pH. Different enzymes have a different optimum temperature and pH at which to function. Most enzymes are denatured at secular temperatures, and deactivated at low temperatures.

The general function of an enzyme is to speed up, or catalyze reactions in the organism. It helps the subst assess to overcome the activation energy barrier that it must reach in order to alteration into the products. This thus enables the cell to have a dynamic metabolism. The enzy me form unchanged after the reaction, and ! merely serves to speed up the rate of reaction. In other cases, the mere presence of the enzyme is a harbinger to a whole cycle...
