Question

Describe the mechanism of enzyme activity?

Answer 1

The basic mechanism by which enzymes catalyze chemical reactions begins with the binding of the substrate (or substrates) to the active site on the enzyme. The active site is the specific region of the enzyme which combines with the substrate. The binding of the substrate to the enzyme causes changes in the distribution of electrons in the chemical bonds of the substrate and ultimately causes the reactions that lead to the formation of products. The products are released from the enzyme surface to regenerate the enzyme for another reaction cycle.

The active site has a unique geometric shape that is complementary to the geometric shape of a substrate molecule, similar to the fit of puzzle pieces. This means that enzymes specifically react with only one or a very few similar compounds.

Answer 2

its not 1 mechanism. 1. is lock n key mech. ie substrate fixes itself in active site of enzyme. 2. is induced fit ie it has enzyme has 3 active sites e1 e2 e3 n subs trate has 3 bindin sites s1 s2 s3 if e1 n s1 bind enzyme rxn takes place. 3 allostreic mech... if u want to get more information then u can get it fromhttp://www.udel.edu/chem/white/C643/Meta... k
