Protein produced in cells that speeds up the rate of biological reactions; the names of many enzymes end in “-ase” (e.g., lipase, amylase). Enzymes are macromolecular biological catalysts that accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.Metabolic […]
