|
Why are enzymes such good catalysts?
|
1) Specificity of substrate binding
2) Optimal arrangement of catalytic gps in active site |
|
|
What are th similarites between enzyme and chemical catalysis?
|
-Both are recovered at the end of the rxn
-Both don't chane the Keq |
|
|
What are the differences between enzyme and chemical catalysis?
|
1)Size: most enz are much larger than their substrates
2)Binding specificity: asymmetric active site -Structural Specificity: dif btw v/ similar molec -Stereospecificity: dif btw stereoisomers |
|
|
What forces improve substrate binding to the active site?
|
-Vad der Waals forces
-Electrostatic Forces -Hydrogen bonding -Hydrophobic interaction |
|
|
What are the 6 types of enzyme mechanisms of catalysis?
|
1) Acid-Base
2) Covalent/Nucleophilic 3) Metal Ion 4) Electrostatic 5) Catalysis through proximity and orientation effects 6) Preferential binding of the transitiokn state complex |
