Aerobic

• What is the site of aerobic respiration?

  Mitochondria
• What are the two reactants of aerobic respiration?

  Glucose and oxygen
• Why is aerobic respiration important for living things?

  It releases energy for cellular activities
• What systems work together to provide glucose and oxygen for respiration?

  Digestive, respiratory, and circulatory systems
• What waste products are removed from the body during respiration?

  Carbon dioxide and water
• In which part of the cell does aerobic respiration occur?

  Inside the mitochondria
• Which types of cells have many mitochondria?

  Muscle cells and root hair cells
• How is energy from respiration used for movement?

  It powers muscle contraction
• What is active transport in root hair cells?

  Moving molecules against concentration gradients
• How does respiration help maintain constant body conditions?

  It releases heat to keep warm
• Why is aerobic respiration considered an exothermic reaction?

  It transfers energy to the environment
• What is the word equation for aerobic respiration?

  Glucose + oxygen → carbon dioxide + water
• How do cells and animals use energy released by respiration?

  • For movement (muscle contraction)
  • Active transport of molecules
  • Building new molecules (carbohydrates, lipids, proteins)
  • Maintaining constant body conditions (keeping warm)
• What are the characteristics of aerobic respiration as an exothermic reaction?

  • Transfers energy to the environment
  • More energy released in products than consumed in reactants
  • Results in a slight increase in temperature
• What is the chemical equation for glucose oxidation?

  C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
