- Respiration
- Respiration
- Chemical Reaction
- Exothermic
- Takes place in all living cells
- Aerobic
- Releases lots of energy as the glucose has been fully oxidised
- glucose + oxygen -> carbon dioxide + water
- Anaerobic
- Releases less energy because the oxidation of glucose is incomplete
- glucose -> lactic acid
- Lactic acid makes our muscles feel tired and achey
- We remove lactic acid by breathing
- lactic acid + oxygen -> carbon dioxide + water
- Metabolism
- The conversion of glucose to starch, glycogen and cellulose is a metabolic reaction
- The use of glucose and nitrate ions to form amino acids that are then used to make proteins is a metabolic reation
- The sum of all the reactions taking place in a cell or the body of an organism
- Respiration is a metabolic reaction
- Photosynthesis is a metabolic reaction
- Exercise
- Aerobic respiration increases which means the bodies cells require more oxygen
- Breathing rate and breathing volume increase
- Heart rate increases to pump the oxygenated blood around the body
- Normally anaerobic respiration takes place in the muscles
- The lactic acid has to be removed from the muscles which requires oxygen
- Oxygen debt-amount of extra oxygen needed after exercise to remove lactic acid from the muscles
- Respiration
