(3 Words) 4. Used by yeast cells and some bacteria to produce Carbon Dioxide and ethyl alcohol (2 Words) 6. Molecules that absorb specific wavelengths of sunlight 8. The reaction taking place in the chloroplast in which the absorption of a photon leads to the formation of atp and nadph. (3 Words) 10. Require oxygen to be completed 11. light-stimulated chemical decomposition: the irreversible decomposition of a chemical compound as a result of the absorption of electromagnetic radiation, especially visible light 12. Process by which mitochondria break down food molecules to produce ATP (2 Words) 15. Supplies energy when oxygen is scarce (3 Words) 16. A group of compounds that pass electron from one to another via redox reactions coupled with the transfer of proton across a membrane to create a proton gradient that drives ATP synthesis. (3 Words) 17. A series of chemical reactions in the cytoplasm of a cell that break down glucose

Down 1. Series of reactions in photosynthesis: a series of reactions that take place in photosynthesis by which carbon dioxide is converted to glucose (2 Words) 2. Phase of photosynthesis where energy from light-dependant reactions is used to produce glycose and additional ATP molecules (3 Words) 5. Electron carrier molecule; when carrying excited electrons it becomes NADPH 7. Green plant pigment used in photosynthesis: the pigment in plants that captures the light energy required for photosynthesis 9. No oxygen required 13. Energy storing molecule in cells. Energy is stored in the molecules bonds and can be used quickly and easily by cells 14. Molecule formed from the breaking down of a phosphate group for ATP
