respiration

• organic meaning


  contains carbon
• respiration


  a chemical reaction that releases energy from organic compounds so that cells can function
• word equation for aerobic respiration

  glucose + oxygen -> carbon dioxide + water (energy)
• symbol equation for aerobic respiration

  C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O
• where does aerobic respiration take place?

  Mitochondria
• where does anaerobic respiration take place?


  cytoplasm
• where do animals get glucose from for respiration


  breakdown of carbohydrates in small intestine

  breakdown of fat and glycogen stores
• where do plants get glucose need for respiration

  during photosynthesis

  breakdown of starch stores
• word equation for anaerobic respiration in plants and yeast

  glucose -> ethanol + carbon dioxide + ( a little bit of energy)
• in anaerobic respiration, glucose is not completely broken down so the rate of reaction is also faster
• Respiration releases some heat energy, but most of it is used to make ATP
• The ATP molecules can be used for

  muscle contraction (animals)

  active transport

  breaking larger molecules into smaller molecules

  to build large molecules from smaller ones to make new materials for cells

  maintaining constant internal body temperature (animals)
• anaerobic respiration in animals

  glucose -> lactic acid (a little energy)
