pH
Which explanation accurately describes why the enzyme is responding as shown?
O At a neutral pH, the enzyme's active site forms attractions with the enzyme, decreasing the rate of the reaction.
O At low and high pH levels, the enzyme's active site forms attractions with the enzyme, increasing the rate of the reaction.
O At a neutral pH, the enzyme's active site changes shape so the substrate can no longer form attractions with the enzyme, denaturing the enzyme.
O At low and high pH levels, the enzyme's active site changes shape so the substrate can no longer form attractions with the enzyme, denaturing the enzyme.
