Study Notes
Enzyme Structure and Function
- Enzymes are biological catalysts, composed of proteins.
- Proteins are made of amino acids linked in polypeptide chains.
- Enzymes speed up reactions without being consumed.
- An enzyme's shape is crucial; its active site complements the substrate's shape.
Types of Enzyme Reactions
- Degradation reactions break down a large substrate into multiple smaller products.
- Synthesis reactions build up multiple smaller substrates into a larger product.
- Example: Hydrogen peroxide + catalyst → oxygen + water (catalysis reaction)
Enzyme Activity and Denaturation
- Enzymes function optimally at specific temperatures and pH levels.
- Changes in temperature or pH can cause enzymes to denature.
- Denaturation alters the enzyme's shape, making the active site non-complementary to the substrate.
- This reduces the reaction rate.
