• what is the word equation for aerobic respiration?

  Glucose + Oxygen -> Carbon Dioxide + Water + Energy
• what is the equation for anaerobic respiration?


  Glucose - > Lactic acid + energy
• where does aerobic respiration take place?

  Mitochondria
• what is aerobic respiration?

  an exothermic reaction which glucose reacts with oxygen to release energy which can be used by cells.
• what is anaerobic respiration?

  Respiration without oxygen.
• what is an oxygen debt?

  Accumulated deficit of oxygen in the body during intense exercise.
• how do muscles store glucose?

  Glycogen
• what is metabolism?

  Metabolism is the process by which the body converts food and drink into energy.
• why can anaerobic respiration lead to muscle fatigue?

  lactic acid builds up in muscles, preventing efficient contraction.
• why is anaerobic respiration less efficient than aerobic respiration?

  glucose is not completely broken down, so less energy is transferred.
• what is the fermentation reaction used for?

  Production of alcohol or bread.
• how is lactic acid transported away from the muscles?

  blood flow through the muscles transports lactic acid to the liver, where it is oxidized back into glucose.
• what is fermentation?

  a type of anaerobic respiration that occurs in yeast cells.
• how do cells use energy transferred by respiration?

  to continuously carry out enzyme-controlled processes which led to the synthesis of new molecules.
