photosynthesis and cellular respiration

  • What are you doing?
  • I'm researching about photosynthesis and cellular respiration.
  • Come with me. I want to show you something.
  • Photosynthesis is the process of when plant organisms turn sunlight into chemical energy.
  • All these plants around us perform photosynthesis.
  • Exactly right! Also the photosynthesis equation is 6CO2+6H20+light energy--> C6H12O6+6O2. This tells you the amount of molecules for each reactant and then the amount of molecules for the products that the reactants get turned into.
  • Carbon Dioxide, water, & sunlight are reactants and glucose & oxygen are products rights?
  • In photosynthesis, Carbon Dioxide (CO2) and water (H2O) go in the chloroplast. Then with sunlight they get turned into glucose (C6H1206) and oxygen (O2).
  • Oh yeah! Cellular respiration is the process of when humans and animals use energy stored in food. Two types of cellular respiration are anaerobic and aerobic respiration. Anaerobic does not require oxygen but aerobic does require oxygen.
  • There are 3 stages of respiration; glycolysis (anaerobic), the Krebs cycle, and electron transport chain (aerobic).
  • Oh okay, but what about cellular respiration?
  • Well, glycolysis breaks down glucose into pyruvic acid molecules with a net gain of 2 ATP molecules also using enzymes and does not require oxygen. (takes place in the cytoplasm)In the Krebs cycle the pyruvic acid goes to the mitochondria and is broken down and carbon dioxide and energy is released. (requires oxygen) In the electron transport chain a series of chemical reactions take place and energy is released. (requires oxygen)
  • What does each stage do?
  • The cellular respiration equation is C6H12O6+6O2-> 6CO2+6H2O+energy
  • So the plants convert sunlight into there energy and we get our energy from the foods we eat. Its like a process
  • Oh wow! I get it now
