Question

drag the terms on the left to the appropriate blanks on the right to complete the sentences. active site catalyst enzyme substrate activation energy inhibitor product denature induced fit high temperatures or changes in ph can blank an enzyme, causing it to lose its shape and biological activity. an enzyme is considered a(n) blank because it speeds up a chemical reaction without being used up. enzymes speed up chemical reactions by lowering the blank, which allows the reaction to proceed much more quickly. the blank between an active site and its substrate often strains bonds and helps the reaction proceed. the specific location within an enzyme molecule where the substrate binds is called the blank. a(n) blank is a molecule that can bind to an enzyme and prevent the enzyme from working. during an enzymatic reaction, a molecule of blank binds to the enzyme and is broken down into one or more molecules of blank, which are released. lactose takes years to break down on its own. but if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. lactase is an example of a(n) blank.

Explanation:

1. High temperatures or pH changes disrupt enzyme structure, a process called denaturation.
2. Enzymes are catalysts as they speed - up reactions without being consumed.
3. Enzymes lower activation energy for faster reactions.
4. Induced fit between active site and substrate strains bonds.
5. The substrate binds to the active site of an enzyme.
6. Inhibitors bind to enzymes and stop them from working.
7. During an enzymatic reaction, substrate binds and is broken into products.
8. Lactase, which speeds up lactose breakdown without changing itself, is an enzyme.

Answer:

1. denature
2. catalyst
3. activation energy
4. induced fit
5. active site
6. inhibitor
7. substrate; product
8. enzyme
