Enzymes
Eric Cuilciにより
1. How they work?
1.1. 2 Models
1.1.1. Locked and Key
1.1.2. Induced fit
2. Regulation inside cells
2.1. Enzyme activity is regulated to ensure control biochemical reactions efficiently. There are four main mechanisms.
2.1.1. Allosteric regulation
2.1.2. Feedback inhibition
2.1.3. Competitive and Non- Competitive inhibition
2.1.4. Covalent modification
3. Types of enzymes
3.1. Metabolic enzymes
3.2. Digestive enzymes
3.3. DNA enzymes
4. Factors affecting enzyme activity
4.1. Temperature
4.1.1. It must be around 37°C,
4.2. Ph
4.2.1. It must be neutral, Ph 7.
4.3. Cofactors and Coenzymes
4.3.1. It increases enzyme activity
4.4. Substrate concentration
4.4.1. It increases enzyme activity
4.5. Enzyme concentration
4.5.1. It increases enzyme activity
4.6. Inhibition
4.6.1. Block enzyme activity
4.6.1.1. Competitive
4.6.1.2. Non-competitive
5. What is it?
5.1. Are proteins that act as a biological catalyst to speed up a chemical reaction.
6. Structure
6.1. Substrate
6.1.1. The molecule that the enzyme acts on.
6.2. Active site
6.2.1. Where the substrate bind.
6.3. Enzyme-substrate complex
6.3.1. Temporary binding between enzyme & substrate.
