Across
- 2. the minimum amount of energy required to start a chemical reaction
- 9. changing the shape and working ability of an enzyme by altering the temperature, pH, ion strength, or solubility of the environment it in
- 10. reaction a process by which one or more starting substances gets converted into one or more different substances
- 11. the ending material(s) or substance after a chemical reaction has taken place
- 12. The number in front of a chemical formula that shows how many molecules or units react or are formed in a chemical reaction
- 13. the starting material(s) in a chemical reaction; found before the arrow in chemical equation
Down
- 1. a molecule that sits in the activesite of an enzyme reducing the rate of biochemical reactions
- 3. A reaction that releases energy in the form of heat; the products have less energy than the reactants
- 4. an abbreviated way of showing how many atoms and their amounts in a molecule
- 5. an abbreviated way of showing a chemicalreaction
- 6. a number written smaller, lower, and behind a chemical symbol; it tells how many atoms of that chemical are found in the molecule
- 7. a substance that speeds up a chemical reaction but is not altered or used up in the process; lowers the activation energy of a reaction
- 8. A chemical reaction in which the products have more energy than the reactants making the overall reaction feel colder
- 14. the energy molecule used by the cell
