The level of protein structure primarily involved in determining enzyme activity is the enzyme.

The Enzymes

Explanation:

The degree of protein structure basically associated with deciding compound action is the protease enzymes.Catalysts are basically globular proteins - protein particles where the tertiary structure has given the atom a for the most part adjusted, ball shape (albeit maybe a squashed ball sometimes). The other kind of proteins (stringy proteins) have long slight structures and are found in tissues like muscle and hair.  Chemicals are natural impetuses (otherwise called biocatalysts) that accelerate biochemical responses in living life forms.They can likewise be extricated from cells and afterward used to catalyze a wide scope of financially significant procedures.  Catalysts are natural atoms (ordinarily proteins) that fundamentally accelerate the pace of for all intents and purposes the entirety of the substance responses that happen inside cells. They are indispensable forever and serve a wide scope of significant capacities in the body, for example, helping in absorption and digestion.  The Models are  DNA polymerase and lactase and liquor dehydrogenase. Various catalysts that catalyze a similar synthetic response are called isozymes

Is their a picture that goes along with it? ?
