Biology

• Energy stores

  • Glucose
  • Sugars
  • Carbohydrates
  • Fats
  • Proteins
• Metabolic processes

  Making larger molecules from smaller ones
• Energy released by respiration

  • Heat
  • ATP
• Types of respiration

  • Aerobic
  • Anaerobic
• Energy


  The ability to do work
• Glucose


  A type of sugar that is often used as an energy store in the body
• Rate of respiration

  The speed at which respiration occurs
• Anaerobic respiration


  Does not require oxygen
• Controlled by enzymes


  Enzymes are proteins that speed up chemical reactions
• Respiration is a process that releases energy
• Aerobic respiration


  Requires oxygen
• Respiration


  The process of breaking down energy stores (such as glucose) to release energy in the form of heat and ATP (adenosine triphosphate)
• Maintaining a steady body

  • Mammals
  • Birds
• Examples of metabolic processes

  • Making larger molecules from smaller ones
  • Contracting muscles (in animals)
• Celular processes

  • Respiration
  • Sucn
• Respiration is affected by

  • Temperature
  • pH
• Aerobic respiration is the type of respiration most commonly used
• Factors affecting the rate of respiration

  • Temperature
  • pH
  • Enzymes
  • Oxygen levels
  • Glucose levels
• What is the word equation for aerobic respiration?

  Glucose + Oxygen----- carbon dioxide+ Water
