Across
  1. 4. (usually a protein) that speeds up a biochemical reaction by lowering its activation energy
  2. 6. Get energy from living or non-living organisms. examples: animals, fungus, people.
  3. 7. Eat only meat example-polar bear
  4. 8. A reaction that overall releases more energy (in the form of heat or light than it absorbs.
  5. 9. Reactions that build larger molecules from smaller ones
  6. 12. A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid.
  7. 13. (substrate) A substance that is changed during a chemical reaction
  8. 20. The synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
  9. 21. energy Energy needed to get a chemical reaction started
  10. 22. A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.
  11. 23. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
  12. 25. Substance that speeds up the rate of a chemical reaction without being permanently altered
  13. 26. A reaction that overall absorbs more energy (in the form of heat or light) than it releases.
  14. 27. Pancake-like stacks of thylakoid membrane
  15. 29. A substance that is made in a chemical reaction
  16. 31. Eat meat and vegetation example-raccoons
Down
  1. 1. The membrane of the mitochondria that is the site of electron transport and chemiosmosis.
  2. 2. Requires oxygen
  3. 3. Eat only vegetation
  4. 5. The overall process by which sunlight (solar/light energy) chemically converts water and carbon dioxide into chemical energy stored in glucose (a sugar/carbohydrate) (this happens on the leaf of a plant)
  5. 10. Reactions The breaking and forming of bonds between different substances during chemical changes
  6. 11. Is without oxygen; usually w/short-spurt, high-energy activities
  7. 14. site Location on an enzyme where the substrate binds
  8. 15. Non-living portion
  9. 16. Reactions that break down larger molecules into simpler compounds.
  10. 17. All of the chemical reactions that occur within an organism
  11. 18. Eat dead materials example-vultures
  12. 19. Fluid-like substance that fills the space between the grana
  13. 24. They get energy from non-living sources most capture energy during photosynthesis to make simple sugars.
  14. 28. A substance present in all living cells that provides energy for many metabolic processes and is involved in making RNA.
  15. 30. When an enzyme's active site loses its specific shape, causing a loss in biological activity
