Respiration

• Respiration


  Taking in of food and combining it with oxygen to make energy
• Energy


  The ability to do work
• Work


  Done when a body is moving
• Respiration


  Glucose + Oxygen
• Anaerobic respiration


  The release of energy from food without oxygen
• Anaerobic respiration in animals

  • Lactic Acid
• Anaerobic respiration in plants

  • Ethanol and Carbon Dioxide
• Anaerobic respiration in animals when exercising and not enough oxygen present

  Makes Lactic Acid (cramp)
• Anaerobic respiration in yeast cells


  Produces ethanol - fermentation
• Respiration


  • There are a lot of steps so is known as a process
  • New substances are produced so is a chemical process
  • All these processes occur in the cell so known as a biological process
• Mitochondrion


  • Many reactions occur in the mitochondrion - RESPIRATION
  • LIVER AND SPERM CELLS HAVE LOTS OF MITROCHONDRIONS FOR ENERGY
• Factors affecting respiration


  • Glucose availability
  • Oxygen
  • Temperature (enzymes - control biological processes)
• Yeast and different temperature experiment
