Flashcards do conjunto (17)
- 1Explain what a chemical reaction is.A process when a set of chemicals changes/transforms into another
- 2Elements/compounds that enter a chemical reaction are _____. Those produced by a chemical reaction are _____.reactants; products
- 3What is activation energy? Give an example.Energy that is involved with chemical reactions regardless of whether the overall chemical reaction releases or absorbs energy; burning paper with a match
- 4What is a catalyst?A substances that speeds up the rate of a chemical reaction by lowering a reaction activation's energy
- 5What is an enzyme?A protein that acts as biological catalysts
- 6What do enzymes do in our bodies?They speed up chemical reactions that take place in cells by lowering activation energy
- 7Explain how an enzyme works during a chemical reactionAn enzyme allows reactants to bond by providing a site where these reactants can be brought together to react. A site reduces the energy needed for a reaction.
- 8What are substrates?Reactants of enzyme-catalyzed reactions
- 9What would happen to the enzymatic reaction if the enzyme lost its shape?The enzyme would not work the same way and might become useless altogether
- 10What are factors that regulate enzyme activity?Temperature, pH, regulatory molecules
- 11Define a catalysta substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
- 12Define an active sitethe specific region of an enzyme where a substrate binds and catalysis takes place or where chemical reaction occurs.
- 13What is an enzyme-substrate complex?The intermediate formed when a substrate molecule interacts with the active site of an enzyme
- 14What is activation energy?the energy which must be provided with potential reactants to result in a chemical reaction
- 15What is an exergonic reaction? What's an example?When energy is released; combustion
- 16What's an endergonic reaction? What's an example?Energy is absorbed; protein synthesis
- 17What's the difference between the two reactions?Endergonic builds up, exergonic breaks down
