How pH affects enzyme activity?

pH also plays a role in enzyme activity. For hydrogen peroxidase, the highest activity was at pH 7. At pH 11, the activity was very low and at pH 1 there was no activity. This is likely because pH affects ionic and hydrogen bonds which are important to enzyme shape and therefore enzyme activity (Reece, et al 2010).

What is the effect of temperature on enzymes?

As with many chemical reactions, the rate of an enzyme-catalysed reaction increases as the temperature increases. However, at high temperatures the rate decreases again because the enzyme becomes denatured and can no longer function.
