Aerobic Respiration

• Respiration


  A chemical reaction which occurs in mitochondria to release energy
• Aerobic respiration

  An exothermic reaction that occurs in animals to produce energy which requires oxygen and glucose as reactants
• Aerobic respiration

  Glucose + oxygen = carbon dioxide + water
• Glucose


  A form of sugar, simple carbohydrates, that is broken down
• Gas exchange

  1. Inhaling oxygen and exhaling carbon dioxide

  2. Oxygen diffuses into the bloodstream

  3. Carbon dioxide diffuses into the alveoli, out of bloodstream to get exhaled
• Diffusion


  A process of gas moving from higher concentration to lower concentration
• Oxygen delivery

  1. Oxygen diffuses into the capillaries

  2. Red blood cells deliver them to cells

  3. Red blood cells carry the carbon dioxide produced by aerobic respiration
• Hemoglobin


  A pigment in red blood cells which combines with oxygen to create oxyhemoglobin
• Respiratory system

  • Nose
  • Mouth
  • Trachea
  • Bronchi
  • Bronchioles
  • Lung
  • Alveoli
  • Diaphragm
• Trachea


  • Has c-shaped cartilage rings to prevent it from collapsing and support it
• Alveoli


  • Adapted by having millions of them
  • Highly folded membrane increases the surface area to make it more efficient and effective
  • Membrane is flexible and elastic so that it could expand easily for the air
  • Membrane is very thin, which offers shorter passage for gas to diffuse
  • Good blood supply is important to keep the gradient high
