4. tissue
similar cells working together

5. organ
group of tissues working together

6. cellular respiration
the breakdown of an energy source by cells to obtain usable energy

7. Enzymes are catalysts.
enzyme

8. catalyst
substances which change other substances without being permanently changed themselves

9. Catalysts are tools.

10. Cellular Respiration
aerobic
aerobic cellular respiration
oxygen

11. aerobic respiration
the process by which cells use oxygen to obtain usable energy from an energy source

12. sugar + oxygen = carbon dioxide + water + energy

13. anaerobic cellular respiration
the process by which cells obtain energy from an energy source without using oxygen

14. carbon
dioxide
energy
sugar
alcohol & lactic acid

15. alcoholic fermentation
produces alcohol and carbon dioxide from glucose
