Bioenergetics, light - Coggle Diagram

- - - - it is converted back to glucose
      - oxygen debt is the amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it form the cells
      - blood flowing through the muscles transports lactic acid to the liver
  - - - use of glucose and nitrate ions in the formation of amino acids and in turn the synthesis of proteins
      - respiration
      - the formation of lipid molecules from one molecule of glycerol and three molecules of fatty acid
      - break down of excess protein to urea for excretion
      - conversion of glucose to starch, glycogen and cellulose
  - - - releases lots of energy
      - happens in the presence of oxygen
      - glucose + oxygen ---> water + carbon dioxide
    - - plants
        
        called fermentation
        
        economic importance in the manufacturing of bread & alcoholic drinks
        
        glucose ---> carbon dioxide + ethanol
      - animals
        
        oxidation of glucose isn't ocmplete
        
        much less energy is transferred than aerobic respiration
        
        glucose ---> lactic acid
    - - The energy transferred provides all the energy needed for living processes
      - Organisms need energy for movement // keeping warm // chemical reactions to form larger molecules
      - exothermic reaction that occurs constantly in all cells
- - - - light intensity: proportional to 1 / (distance from light source)^2 // as light intensity increases so does RoR
      - carbon dioxide concentration: as it increases so does the rate of photosynthesis // more carbon dioxide available
      - temperature: reaction controlled by enzymes so more temp, more KE, so mroe photosynthesis // enzymes denature at about 40°C so rate decreases
      - amount of chlorophyll: more chloroplasts with more chlorophyll means more photosynthesis can happen
