Across
- 2. organic molecules, such as glucose, that organisms use for chemical energy
- 4. second stage of photosynthesis in which carbon atoms from carbon dioxide are combined, using the energy in ATP and NADPH, to make glucose
- 6. green pigment in a chloroplast that absorbs light energy during the light reactions of photosynthesis
- 7. energy-carrying molecule that cells use to power their metabolic processes; provides the cell with an immediate usable form of energy
- 8. within the chloroplast, consists of sac-like membranes, known as thylakoid membranes
- 12. common name of a plant-like protist, which contains chloroplasts and makes food by photosynthesis
- 15. single-celled prokaryotic organism that is a member of the Bacteria domain
- 20. third stage of cellular respiration, which occurs on the inner membrane of mitochondria, requires oxygen, and produces up to 34 molecules of ATP
- 23. structure found in all cells that is the site of protein synthesis
- 24. fluid-filled space inside a chloroplast where the second stage of photosynthesis (Calvin cycle) occurs
- 25. series of electron-transport molecules that pass high-energy electrons from molecule to molecule and capture their energy
- 26. a protein that acts as a biological catalyst, increasing the rate of a biochemical reaction
Down
- 1. theory that eukaryotic organelles such as mitochondria evolved from ancient, free-living prokaryotes that invaded primitive eukaryotic cells
- 3. basic unit of structure and function of living things
- 5. a representation of a chemical reaction that displays the reactants and products with chemical formulas; multiple reactants or products are separated with a plus sign, and reactants are separated from the products with a yield arrow
- 9. flattened sac of membrane inside a chloroplast where the first stage of photosynthesis (light reactions) occurs
- 10. molecules that accept and temporarily hold high-energy electrons
- 11. first stage of photosynthesis in which light energy from the sun is captured and changed into chemical energy that is stored in ATP and NADPH
- 13. organism that makes its own food
- 14. structure within the cytoplasm of a cell that is enclosed within a membrane and performs a specific job
- 16. simple sugar that all living things use to store and transport energy
- 17. group of molecules, including chlorophyll, in the thylakoid membrane of a chloroplast that captures light energy
- 18. double-stranded nucleic acid that stores genetic information; also known as deoxyribonucleic acid
- 19. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar
- 21. the ability to do work
- 22. short-term energy carrier; temporarily stores energy during photosynthesis
