Respuesta :
A cell is able to perform degradative and biosynthetic reaction in part due to ENZYMATIC proteins attached to the membrane of the cell.
The given blank can be filled with the term enzymatic.
The enzymatic proteins are the proteins, which can enhance, activate or deactivate a particular reaction taking place in the cell. The enzymes come and bind to the membrane receptors found in the cell membrane. Binding of the enzymes send signals molecules for the activation of deactivation of the reactions.
