Enzyme
What is Enzyme
-
Biocatalyst : A molecule that accelerates a chemical reaction without being altered itself (Enzyme are not change)
-
Enzyme Activity
Enzyme Kinetic
-
E + S <=k1,k2=> ES --k2--> E + P

How Enzymes Work
-
Fisher's Template Theory
Lock and Key model
Active site has a fixed , The substrate has a shape that fits the enzyme active site to form ES (enzyme-substrate complex)

Enzyme Structure
The active site contains substrate binding site and catalytic site , is the shape of a three-dimensional cleft that is composed of amino acids from different residues of the primary amino acid sequence.
The enzyme binds better or less with the substrate, an additional site of enzyme for an effector or modulator to bind to resulting in conformation change of active site or substrate binding site.
