Explanation:
- Enzymes are biological catalysts that speed up biochemical reactions.
- A substrate is the molecule that the enzyme acts upon and converts to product.
- An active site is the part of the enzyme where the substrate binds to it. Active sites contain a specific amino acid sequence and conformation which make it easy for the substrate to bind.
- Enzymes are stringently substrate specific i.e. only a certain substrate can fit in and bind to the active site of a specific enzyme, just like only one key can fit into a specific lock.
