Study Notes
Enzymes Overview
- Enzymes are biological catalysts that facilitate and speed up chemical reactions in cells.
- They are primarily composed of proteins, which gives them structural and functional properties.
Mechanism of Enzyme Action
- Enzyme function follows a specific mechanism represented as:
- E + S (enzyme + substrate) binds to form E-S (enzyme-substrate complex), which then transforms into E-P (enzyme-product complex), releasing the products and regenerating the enzyme.
Active Site Interaction
- The active site of an enzyme is where the substrate binds; this interaction is crucial for the catalytic activity.
Binding Capacity
- An enzyme is capable of binding multiple substrate molecules at different times, not just one at a time.
Enzyme Reusability
- Enzymes are not consumed in the reactions they catalyze, allowing them to be used repeatedly for multiple reactions.
