Across
  1. 2. The product of glycolysis; almost half of glucose; formula is C3H4O3
  2. 3. The process of cellular respiration that takes place in the presence of oxygen gas to produce ATP energy from pyruvic acid. Products are water, energy (ATP), and CO2.
  3. 5. The form of anaerobic respiration in which the byproduct will be ethyl alcohol.
  4. 6. The location where glycolysis occurs.
  5. 8. A sugar molecule created by photosynthesis and broken down by glycolysis; formula is C6H12O6
  6. 10. A series of protein complexes embedded in membranes that create a gradient for passing electrons; they help charge NADPH
  7. 12. The small openings on the bottom of a leaf that allow oxygen and carbon dioxide gasses to pass through. They are opened and closed by guard cells.
  8. 15. The first reaction of photosynthesis that creates ATP and NADPH energy molecules using sunlight and water; happens in the thylakoid membrane of a chloroplast
  9. 18. The membrane of a thylakoid in a chloroplast where the light-dependent reaction creates ATP and NADPH energy molecule
  10. 20. Any colored material found in plant or animal cells. They absorb and reflect different wavelengths of light.
  11. 22. The process used by all living organisms to break sugar into available ATP energy; happens in the mitochondria
  12. 23. The open space inside the chloroplast where the light-independent reaction takes place; where glucose is created during photosynthesis
  13. 24. The process used by plants and algae to convert water, carbon dioxide, and energy from the sun into a glucose sugar; happens in the chloroplast
  14. 25. The organelle in the plant cell that is responsible for photosynthesis; it looks like a disk with stacks of disks in the center
  15. 26. An energy-carrier molecule that is formed during the light reaction and used in the Calvin cycle; formed from NADP+, water, and light
Down
  1. 1. A form of anaerobic respiration in which the byproduct will be lactic acid.
  2. 4. A nucleic acid molecule containing two phosphates that can be changed to an ATP energy molecule by adding a phosphate
  3. 7. The second reaction of photosynthesis that uses small energy molecules and carbon dioxide to form the glucose sugar; happens in the stroma of the chloroplast. (AKA Dark Cycle or LIGHT Independent reaction)
  4. 9. Two reactants of photosynthesis and products of aerobic respiration. They are used to create energy molecules and glucose.
  5. 11. An organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Ex: plant
  6. 13. The organelle that releases ATP energy molecules from sugar (pyruvic acid) molecules during respiration.
  7. 14. A nucleic acid that is a source of stored energy at the cellular level; consists of adenine, ribose sugar, and three phosphates
  8. 16. An organism that eats other plants or animals for energy and nutrients, ex: dog
  9. 17. The process that breaks glucose down into two molecules of pyruvic acid/pyruvate in the cytoplasm.
  10. 19. Process by which pyruvic acid is broken down into available ATP energy without the use of oxygen. By Products will be lactic acid or ethyl alcohol.
  11. 21. The substance in the chloroplast that absorbs light waves from the sun; it reflects green light
