What is the role of enzymes in living tissues?

Enzymes are very important for living organisms. They are found not only in the organisms of highly organized animals. Enzymes are also found in unicellular organisms. For example, in the lysosomes of protozoa. Enzymes can perform various functions in the tissues of living organisms. They act as catalysts for various chemical reactions. Certain enzymes trigger certain reactions. Various types of enzymes are secreted in tissues. Due to this, the reactions take place at different temperatures and ambient conditions.
