What 2 environmental conditions affect enzyme activity

pH & Temperatures

Explanation:

pH affects the charges of the functional amino side groups of the amino acids that make up the protein of the enzymes - through changes in ionization. These charges are significant in maintaining the shape of the protein enzyme through forces of attractions such as hydrogen and sulfide bonds. Changes in charges affect these bonds hence denature the protein.

Temperature does not change the charges of the side groups but breaks these same bonds. This happens by giving these molecules high kinetic energy enough to escape the forces of the bonds - hence denaturing the protein enzyme.
