Enzymes can be found in all body tissues and fluids. Intracellular enzymes catalyse all reactions that take place in metabolic pathways. Enzymes in the plasma membrane control catalysis in cells in response to cellular signals, and enzymes in the circulatory system control blood clotting.
The majority of critical life processes rely on Enzyme functions. Enzymes are made up of a linear chain of amino acids that form a three-dimensional structure. The sequence of amino acids defines the structure, which in turn identifies the enzyme's catalytic activity. The enzyme's structure denatures when heated, resulting in a loss of enzyme activity that is typically temperature dependent.
