Across
- 4. (usually a protein) that speeds up a biochemical reaction by lowering its activation energy
- 6. Get energy from living or non-living organisms. examples: animals, fungus, people.
- 7. Eat only meat example-polar bear
- 8. A reaction that overall releases more energy (in the form of heat or light than it absorbs.
- 9. Reactions that build larger molecules from smaller ones
- 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.
- 13. (substrate) A substance that is changed during a chemical reaction
- 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.
- 21. energy Energy needed to get a chemical reaction started
- 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.
- 23. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
- 25. Substance that speeds up the rate of a chemical reaction without being permanently altered
- 26. A reaction that overall absorbs more energy (in the form of heat or light) than it releases.
- 27. Pancake-like stacks of thylakoid membrane
- 29. A substance that is made in a chemical reaction
- 31. Eat meat and vegetation example-raccoons
Down
- 1. The membrane of the mitochondria that is the site of electron transport and chemiosmosis.
- 2. Requires oxygen
- 3. Eat only vegetation
- 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)
- 10. Reactions The breaking and forming of bonds between different substances during chemical changes
- 11. Is without oxygen; usually w/short-spurt, high-energy activities
- 14. site Location on an enzyme where the substrate binds
- 15. Non-living portion
- 16. Reactions that break down larger molecules into simpler compounds.
- 17. All of the chemical reactions that occur within an organism
- 18. Eat dead materials example-vultures
- 19. Fluid-like substance that fills the space between the grana
- 24. They get energy from non-living sources most capture energy during photosynthesis to make simple sugars.
- 28. A substance present in all living cells that provides energy for many metabolic processes and is involved in making RNA.
- 30. When an enzyme's active site loses its specific shape, causing a loss in biological activity
