Ch11+12 gas exchange&reespiration

• properties of surface

  thin surface

  large surface area

  good blood supply

  good ventilation
• thin surface

  to allow fast diffusion of gases
• large s.a

  to allow the diffusion of many molecules at the same time
• good blood supply

  to take gasses to and from the exchange surface
• good ventilation

  for good supply of oxygen an removal of carbon dioxide
• ventilation/breathing

  is the act of moving air in and out of the lungs changing the thorax's volume
• gas exchange

  change of gasses across a gas exchange surface
• respiration

  is the chemical reaction that breaks down nutrient molecules in living cells to release energy
• uses of energy

  muscle contraction

  protein synthesis

  cell division

  active transport

  growth

  passage of nerve impulses

  maintenance of a constant body temperature
• aerobic respiration

  the chemical reaction in the cell that uses oxygen to break down nutrient molecules to release energy
• anaerobic respiration

  the chemical reaction in the cell that breaks down nutrient molecules to release energy without using oxygen
• aerobic respiration word formula

  Glucose + Oxygen --> Carbon dioxide + Water
• aerobic resp. chem. formula

  C6H12O6+6O2-->6CO2+6H2O
• anaerobic resp excercise word form

  Glucose -living cell-> lactic acid
• anaerobic resp workout chem formula

  C6H12O6-->2C3H6O3
• anaerobic resp yeast word formula

  glucose--->alcohol+carbon dioxide
• anaerobic resp yeast chem formula

  C6H12O6--->2C2H5OH+2CO2
