Which statement about enzymes is true? they are large molecules that decrease the rate of reactions in the body. they are large molecules that increase the rate of biologicallyimportant reactions. they slow the rate of chemical reactions. they are permanently changed in the course of a reaction.

The correct answer is that they are large molecules that increase the rate of biologically important reactions.

Explanation:

The biological molecules made up of proteins, which substantially accelerate the rate of almost all the chemical reactions that occurs within the cells are known as enzymes. They play an essential role and are essential for life and function in a broad range of vital functions in the body, like facilitating metabolism and digestion.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.
