Question

metabolism is the all the chemical reactions within an organism, what happens when an enzyme is either not formed properly or non existent? What happens in the process being performed? Do you have any examples?

Answer 1

All enzymes are proteins with an exception of catalytic RNA molecules and their catalytic activity depends upon the integrity of their native conformation. If the enzyme is not formed properly or denatured or dissociated into subunits their catalytic activity is usually lost. If the enzyme is broken down into its compenents amino acids, their ability to perform a reaction is lost.

Some enzymes require chemical groups than their amino acid residues for activity. Others require an additional chemical component called cofactor. These might be an inorganic ions or complex organic metalloorganic molecule called coenzyme.

ATP + D-glucose ADP + D-glucose-6-phosphate

This reaction is characterized by glucose phosphotransferase where the transfer of a phosphate group from ATP to glucose.
