III.1 Catalysis
8 important questions on III.1 Catalysis
How is enzyme specificity brought about?
What happens to a system when it is in the transition state?
What are the general mechanisms enzymes utilize to achieve catalysis?
- Electrostatic catalysis
- Acid-base catalysis
- Covalent catalysis
- Metal ion catalysis
- Nucleophilic attack
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What is electrostatic catalysis?
What is acid-base catalysis? What are the three forms?
- General acid catalysis: a process in which (partial) proton transfer from an acid lowers the free energy of a reaction's transition state.
- General base catalysis: accelerates the rate of a reaction by (partial) proton abstraction
- Concerted acid-base catalysis: a combination of general acid catalysis and general base catalysis
What is covalent catalysis?
What is metal ion catalysis?
What is a nucleophilic attack?
