Chapter 8 Biology

2. Any nonprotein molecule or ion that is required for the proper functioning of an enzyme.
4. non protein molecule that activated the enzyme, can be viatmins or made from vitamines
6. respiration, the process by which cells use oxygen to produce energy from food
8. Alcohol made by converting starches and sugars from plant material into alcohol and CO2.
13. bonds, the attractive force that holds atoms or ions together
14. a substance that causes or hastens a chemical reaction; any agent that causes change
16. proteins that act as biological catalysts
17. energy, Energy needed to get a reaction started
20. molecules, non-carbon based molecules
21. strength, energy required to break a bond
22. An organelle found in plant and algae cells where photosynthesis occurs
23. long linear chains of polypeptides

1. Conversion of light energy from the sun into chemical energy.
3. involved in the synthesis of organic molecules from carbon dioxide and water.
4. Cycle, energy from ATP and NADPH is used to build sugars
5. respiration, the process by which cells use oxygen to produce energy from food
7. energy, energy available to do work
9. acid, product of fermentation in many types of cells, including human muscle cells
10. respiration, Respiration that does not require oxygen
11. lesser amount of hydrogen ion concentration, higher pH
