Bio CK12 2.23 Photosynthesis Summary
Across
- 3. basic unit of structure and function of living things
- 4. energy-carrying molecule that cells use to power their metabolic processes; provides the cell with an immediate usable form of energy
- 5. organelle in eukaryotic cells that uses energy stored in glucose to make ATP, which cells can use for energy.
- 7. second stage of cellular respiration in which two pyruvate molecules from the first stage react to form ATP, NADH, and FADH2 in the presence of oxygen
- 11. simple sugar that all living things use to store and transport energy
- 13. organic compound that supplies energy to the body, such as sugar and starch
- 14. organism that makes its own food
- 16. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar
- 17. an electrochemical gradient across the thylakoid membrane and the inner membrane of the mitochondrion; due to concentration differences of both positive charges and hydrogen ions
- 18. large, complex carbohydrate found in foods such as grains and vegetables that the body uses for energy
- 20. third stage of cellular respiration, which occurs on the inner membrane of mitochondria, requires oxygen, and produces up to 34 molecules of ATP
- 21. short-term energy carrier; temporarily stores energy during photosynthesis
- 22. second stage of photosynthesis in which carbon atoms from carbon dioxide are combined, using the energy in ATP and NADPH, to make glucose
- 23. the change of state from a gas to a liquid
- 24. flattened sac of membrane inside a chloroplast where the first stage of photosynthesis (light reactions) occur
- 25. a biochemical process in which cells break down glucose and oxygen to make carbon dioxide, water, and ATP for energy
- 27. structure within the cytoplasm of a cell that is enclosed within a membrane and performs a specific job
Down
- 1. 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
- 2. series of electron-transport molecules that pass high-energy electrons from molecule to molecule and capture their energy
- 6. short-term energy carrier; temporarily stores energy during cellular respiration
- 8. molecules that accept and temporarily hold high-energy electrons
- 9. splitting water by light; produces the hydrogen ions and electrons used in light reactions and oxygen atoms
- 10. process in which an organism builds low-energy inorganic CO2 into high-energy organic molecules like glucose
- 12. organic molecules, such as glucose, that organisms use for chemical energy
- 15. organelle in the cells of plants and algae, that contains chlorophyll and is the site of photosynthesis
- 19. the ability to do work
- 26. an atom or group of bonded atoms that has a positive or negative charge
