The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart. Does photosynthesis require cellular respiration? Photosynthesis and cellular respiration are complementary biochemical reactions. Photosynthesis requires the products ofRead More →
Previously, scientists believed that anoxygenic evolved long before oxygenic photosynthesis, and that the earth’s atmosphere contained no oxygen until about 2.4 to 3 billion years ago. … This is also long before cyanobacteria — microbes that were thought to be the first organisms to produce oxygen — existed. What cameRead More →
Supposed Myth: Cockroaches don’t breathe oxygen. … They do, however, breathe oxygen. Scientists are investigating whether or not roaches sometimes hold their breath to prevent water loss. The same tubes – called spiracles – that roaches use to breathe are also used to transport water vapor out. How many spiraclesRead More →
But instead of lungs, they use gills. … As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that’s dissolved in the water. Then the blood moves through the fish’s body to deliver the oxygen, just like in humans. How doRead More →
Terms in this set (4) Elodea, a plant and autotroph can take on photosynthesis in the light and cellular respiration. … Cellular respiration can happen in darkness, so the bottles that turned yellow means the organisms went through the process of Cellular respiration. Can cellular respiration happen at night? CellularRead More →
The source of energy that is used to power the movement of contraction in working muscles is adenosine triphosphate (ATP) – the body’s biochemical way to store and transport energy. However, ATP is not stored to a great extent in cells. So once muscle contraction starts, the making of moreRead More →
The Light Reactions The energy is then temporarily transferred to two molecules, ATP and NADPH, which are used in the second stage of photosynthesis. ATP and NADPH are generated by two electron transport chains. During the light reactions, water is used and oxygen is produced. What are the 3 stagesRead More →
Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid. Though it does not produce as much energy as aerobic respiration, it gets the job done. Does anaerobic respirationRead More →
-In anaerobic respiration, the final electron acceptor is an inorganic substance other than oxygen, such as nitrate, sulfate, or carbonate. What are the hydrogen electron acceptor for aerobic and anaerobic respiration? This electron acceptor is either oxygen in aerobic respiration or, in anaerobic bacteria and archaea, some other inorganic moleculeRead More →
