Chapter 6: Energy Flow in the Life of a Cell
Across
- 3. provides the muscle with energy to contract. they pick up an energy charge at an exergonic reaction, move within the cell, and release the energy to drive an endergonic reaction
- 4. when energy is converted from one form or another , the amount of useful energy decreases
- 5. chemical reactions that take place in organisms required to maintain life.
- 8. molecules that speed up the rate of reaction without them being used up or permanently altered
- 9. Made up of adenine, ribose, and two phosphate groups, has one less phosphate than ATP, a high energy bond between the second and third is broken when turned into ADP
- 10. non protein molecules that help enzymes function properly. water-soluble vitamins are used to help the body make coenzymes
- 13. a reaction that requires a net input of energy, if the products contain more energy than the reactants
- 15. a tendency a molecule has towards loss of complexity, orderliness and useful energy
- 16. that is stored or conserved in a substance
- 17. energy can neither be created or destroyed by ordinary processes
- 18. light, heat, and energy
- 19. when a poison or drug enters the enzyme and blocks the substrate from being able to be broken apart
- 23. Primary energy carrier, made up of adenine, ribose, and three phosphate groups, has more energy than ADP
- 24. the substance an enzyme works on
- 25. chemical reactions linked in sequences
- 27. energy of movement
- 28. biological catalysts, composed of proteins and synthesized by living organisms. catalyze reactions. very specific to the substrate.
- 29. atoms or molecules that are the reactants for an enzyme-catalyzed chemical reaction
- 30. molecules that hold electrons that have energy in them and transport them to other places
Down
- 1. any form of regulation where the regulatory molecule binds to an enzyme someplace other than the active site
- 2. the energy “push” to start the chemical reaction
- 6. a reaction that involves an endergonic reaction receiving its energy from the exergonic reaction
- 7. describe the quantity and quality of energy
- 11. When the end product of a reaction interferes with the enzyme that helped produce it
- 12. the capacity an organism has to do work (a force acting upon an object that causes the object to move)
- 14. A substance altered during a chemical reaction
- 15. Accompanied by the release of energy
- 20. A substance created as a result of a chemical reaction
- 21. converted to kinetic energy
- 22. a process that can create or destroy chemical bonds that hold atoms together
- 26. a “pocket” for the enzyme. fit (most of the time) perfectly with the substrate as a lock and key
