What are enzymes?
Ø All living organisms in the world should possess TWO fundamental properties
Ø They are:
(1). Must be able to self-replicate
(2). Must be able to catalyze chemical reactions efficiently and selectively
Ø Enzymes are the molecules which enables each living entity to do these two fundamental activities
Ø Enzymes are better known as biological catalysts
Ø Almost all enzymes are highly specialized proteins
Ø Ribozymes: RNA molecules with catalytic properties
Ø Abzymes: antibodies with catalytic properties
What is enzyme regulation?
Ø Enzyme regulation definition: “Process, by which cells can turn on, turn off, or modulate the activities of various metabolic pathways by regulating the activity of enzyme”
Ø Enzymes have extraordinary catalytic power
