* Blood: blood must be kept at a certain pH to ensure the

haemoglobin can bond to oxygen. Otherwise, the formation of

carbonic acid by dissolved carbon dioxide can cause anaemia and

oxygen deprivation. * Plants: many plants require a certain soil

pH, otherwise they are unable to grow. * Bacteria: most bacteria

have a certain range of pH which they grow best in. Outside this

range, growth can be stunted or even prevented entirely. * Enzymes:

Like bacteria, some enzymes work best in certain pH ranges, but

will almost cease entirely when not.
