  1. 5. a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances
  2. 6. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers (cristae)
  3. 7. the source of energy for use and storage at the cellular level
  4. 13. the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight
  5. 14. the process of breaking down food by mechanical and enzymatic action in the alimentary canal into substances that can be used by the body.
  6. 15. an organism deriving its nutritional requirements from complex organic substances.
  7. 16. Fermentation an anaerobic process in which the microorganisms (e.g., bacteria, yeast, and fungi) hydrolyze and ferment the microalgal polysaccharides such as starch, glycogen, and cellulose into ethanol and carbon dioxide.
  8. 17. a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.
  9. 19. the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

  1. 1. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
  2. 2. a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates
  3. 3. the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
  4. 4. an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide
  5. 8. Acid Fermentation a type of anaerobic respiration (or fermentation) that breaks down sugars to produce energy in the form of ATP
  6. 9. Cycle the sequence of reactions by which most living cells generate energy during the process of aerobic respiration
  7. 10. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
  8. 11. Respiration the respiration which occurs in the absence of oxygen to produce the energy
  9. 12. Respiration A chemical process in which oxygen is used to make energy from carbohydrates (sugars)
  10. 18. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
