RESPIRATION

• what is the word equation for aerobic respiration?

  GLUCOSE + OXYGEN -> CARBON DIOXIDE + WATER + ENERGY
• what is the symbol/chemical equation for respiration?

  C6 H12 O6 + 6O2 -> CO2 + 6H2 0 + ENERGY
• why is respiration needed for movement?

  for muscle contraction
• why is respiration needed for active transport?

  for movement of particles from a low concentration to a high concentration
• why is respiration needed for chemical reactions in the body?

  for your metabolism
• what does anaerobic respiration makes us feel?

  • tired
  • sore muscles
  • out of breath
  • hot
• what is the word equation for anaerobic respiration in humans?

  GLUCOSE -> LACTIC ACID + ENERGY
• why do you continue to breath hard after exercise?

  your body is in oxygen dept tyring to brake down lactic acid
• what is the word equation for braking down lactic acid?

  LACTIC ACID + OXYGEN -> CARBON DIOXIDE + WATER
• what is the word equation for anaerobic respiration in yeast?

  GLUCOSE -> ETHANOL + CARBON DIOXIDE
• similarities of anaerobic respiration in humans and yeast:

  • both use glucose as the substrate
  • both release energy
• differences of anaerobic respiration in humans and yeast:

  • products are different (humans = lactic acid, yeast = ethanol and CO2)
• similarities of aerobic and anaerobic respiration:

  • both use glucose as a substrate
  • both release energy
• differences of aerobic and anaerobic respiration:

  • aerobic produces more energy per molecule of glucose
  • aerobic uses oxygen
  • products are different (aerobic = CO2 and water, anaerobic = lactic acid)
• how do you calculate your percentage change in heart rate?

  pulse rate after exercise - resting pulse rate / resting pulse rate X 100
