Respiration

• Respiration is the process whereby glucose is broken down to produce energy.
• The currency of energy is called adenosine triphosphate (ATP)
• There are 2 types of respiration: aerobic respiration and anaerobic respiration
• Aerobic respiration is a process whereby oxygen is used to breakdown glucose into carbon- dioxide, water and energy.
• Aerobic respiration occurs in the mitochondrion of the cell and produces a large amount of energy.
• the word equation for aerobic respiration is: glucose + oxygen -> carbon dioxide + water + energy

  (reactant, condition, product)
• the balanced chemical or molecular formula for aerobic respiration is: C6H12O6(aq)+ 6O2(g) ——> 6CO2 (g)+ 6H2O (l) + 32 ATP or 2880 KJ mol-'
• all acids are aqueous
• Anerobic respiration is a process whereby glucose is brokendown without oxygen to produce energy.
• both plants and animals carry out anerobic respiration but the products are different.
• the worded equation for anerobic respiration in plants is: glucose ---> ethanol + carbon- dioxide + energy
• the balanced chemical/ molecular equation for anerobic respiration in plants is: C6H12O6(aq) + 2C2H5OH(l) + 2CO2(g) + 2 ATP or 210 KJ mol-'
• the balanced chemical/ molecular equation for anerobic respiration in animals is: C6H12O6(aq) ---> 2C3H6O3(aq) + 2 ATP or 150 KJ mol-'
• the worded equation for anerobic respiration is in animals is: glucose --> lactic acid + enery
• The enzyme ATPase helps to produce the ATP molecule
