1. enzymes speed up chemical reactions by lowering the which allows the reaction to proceed much more quickly.
2. during an enzymatic reaction, a molecule of binds to the enzyme and is broken down into one or more molecules of which are released.
3. the between an active site and its substrate often strains bonds and the reaction proceed
4. the specific location within an enzyme molecule where the substrate binds is called the
5. 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 an:
6. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity. an: is a molecule that can bind to an enzyme and prevent the enzyme from working.
7. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.

Enzymes are proteins that contains ribonucleic acid (RNA) .An enzyme binds to one or more reactant Molecule in order to catalyze a reaction.

Explanation:

1. Enzymes speed up chemical reactions by lowering the Activation Energy, which allows the reaction to proceed much more quickly.

2. During an enzymatic reaction, a molecule of Substrate binds to the enzyme and is broken down into one or more molecules of  product, which are released.

3. The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed

4. The specific location within an enzyme molecule where the substrate binds is called the Active site.

5. 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 an enzyme

6. High temperatures or changes in pH can an enzyme, causing it to lose its shape and biological activity. An  inhibitor  is a molecule that can bind to an enzyme and prevent the enzyme from working.

7. An enzyme is considered a Catalyst because it speeds up a chemical reaction without being used up.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
