To transport oxygen in the blood
2. The specific area on an enzyme where a substrate binds is called the:
Product site
Inhibitor site
Active site
Binding pocket
3. Enzymes are biological that speed up the rate of biochemical reactions without being used up in the process.
4. The model describes how an enzyme's active site changes shape slightly to bind to its specific substrate.
