What are the essential roles that enzymes play in cells?
Enzymes are macro molecular biological catalysts. They accelerate chemical reactions.
Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life. They increase the
reaction rate by lowering its activation energy.
Enzymes are indispensable for signal transduction and cell regulation.
They generate movement by bringing about muscular contractions.
They also help to transport cargo around the cell as part of the cytoskeleton.
Enzymes play an important function in the digestive system of animals.
Enzymes are known to catalyse more than 5,000 biochemical reaction types.
