Enzymes crossword

3. If this increases the rate of the reaction also increases because there are more active enzymes.
4. The model of the enzyme that shows the substrate fitting perfectly into the active site.
7. A specific type of enzyme inhibition characterized by an inhibitor binding to an allosteric site resulting in decreased efficacy of the enzyme.
8. Enzyme activity increases with this; more collision between substrate molecules and the enzyme.
9. It is loaded into the active site of the enzyme.
12. The energy necessary to turn the substrate into a product.
13. Is a structural change in a protein that results in the loss (usually permanent) of its biological properties.
14. Large and complex molecules that play many critical roles in the body.
15. Molecule that bind to the enzyme and inhibit the enzymes function.

1. The temperature at which an enzyme catalyses a reaction at the maximum rate.
2. Change in the shape of an enzyme's active site that enhances the fit between the active site and its substrate(s).
5. A substance that reduces the activity of an enzyme by entering the active site in place of the substrate whose structure it mimics.
6. A type of protein that speeds up a chemical reaction in a living thing.
10. The specific region of an enzyme where a substrate binds and catalysis takes place or where chemical reaction occurs.
11. Specific pH at which an enzyme works the fastest.
