respiration

• respiration is a chemical reaction which happens in almost every cell of the body to produce energy from nutrient molecules
• energy from respiration can be used in:

  1. protein synthesis
  2. cell division
  3. active transport
  4. maintaining body temp
  5. growth
• breathing is the process of moving air in and out of the lungs to facilitate gas exchange
• respiration:

  1. aerobic: glucose broken down using oxygen
  2. anaerobic: glucose broken down without oxygen
• C6H12O6 + O2 = 6CO2 + 6H2O
• mitochondria is the power house of the cell therefore respiration occurs here
• aerobic respiration is the series of chemical reactions in cells that use oxygen to break down nutrient molecules to release energy
• anaerobic respiration is the series of chemical reactions in cells that don't use oxygen to break down nutrient molecules to release energy
• glucose = lactic acid
• glucose = alcohol + co2
• C6H12O6 = 2C2H5OH + 2CO2
• pro of anaerobic respiration:

  1. release in energy in the absence of oxygen
• cons of anaerobic respiration:

  1. build up lactic acid in muscles
  2. small amount of energy released|
  3. build up oxygen debt
• Breathing:

  1. intake of oxygen and release of carbon dioxide
  2. physical process
  3. involves breathing organs
• Respiration:

  1. breakdown of food to release energy
  2. bio chemical process
  3. happens at a cellular level
