Enzymes are biological molecules with specific characteristics. Choose the three characteristics that best describe enzymes.
Speeds up chemical reactions by adding energy
Reusable and specific
Speeds up chemical reactions by lowering activation energy

One time use
Which statement would best describe what would happen to this enzyme if the external environment went from an optimal pH of 5 to a pH of 3?
The enzyme would denature causing it to change shape so the substrate will not bind correctly.
The enzyme and substrate complex will neutralize the solution to continue the reaction.
The substrate would denature, causing it to change shape and the reaction will not occur.
The enzyme would remain unchanged.
