Respiration

Respiration is not 'breathing in and out':

• Respiration is the process of transferring energy from glucose.
• It is exothermic.
• EXAMPLES of how organisms use the transferred energy:
  • 1. Proteins from amino acids (build up larger molecules from small ones)
  • 2. Allow muscles to contract (in animals)

Aerobic respiration:

• Aerobic respiration uses oxygen:
  • glucose + oxygen -----> carbon dioxide + water
• Anaerobic respiration is without oxygen:
  • glucose -----> lactic acid
• Anaerobic respiration in plants + yeast:
  • glucose -----> ethanol + carbon
