Crossword 1: Enzyme Activity

3. Type of inhibitor that effects the enzyme which changes the shape of the active site causing the reaction rate to be lower.
5. Chemical that acts as a non-competitive inhibitor by reacting with sulfhydryl groups to disrupt disulfide bonds.
7. A molecule that works against the reaction causing it to slow down. There are two types.
10. Substrate used in the enzyme action lab.
11. The catalytic region of the enzyme where it binds to the substrate and the reaction occurs.
13. Enzyme found in potatoes that is responsible for the darkening of fresh peeled potatoes and is also known as tyrosinase or catechol oxidase.
15. What happens to an enzyme when it is exposed to extreme heat and the proteins of the enzyme unfold and become misshapen.
16. This is the name for when the enzyme and the substrate are binding and forming product at the fastest possible rate.

1. Metal ions or organic molecules that must be present in addition to enzymes for a reaction to occur.
2. The concentration of substrate at which production of product is half maximal.
4. acid Chemical that acts as a competitive inhibitor and has a similar structure to catechol.
6. The molecule that the enzyme binds to in order to complete the reaction more quickly.
8. A molecule that when present increases the rate of reaction without being consumed in the reaction.
9. Type of inhibitor that has a similar shape as the substrate which slows down the reaction rate by blocking the substrate from binding to the enzyme.
12. A type of catalyst.
14. dilution Method of dilution that involves using a starting concentration and then decreasing the concentration from which this sample is again diluted. This process continues until the desired concentration is reached.
