Respiration

• What is the main focus of the video?

  Different types of respiration
• Why is respiration important for energy?

  It releases energy from glucose molecules
• What is the process called that releases energy from glucose?

  Cellular respiration
• How is cellular respiration described in terms of energy?

  As an exothermic reaction
• What does the term 'exothermic' mean in this context?

  It means the reaction releases energy
• What are three examples of how organisms use energy?

  Building larger molecules, muscular contraction, maintaining temperature
• What is metabolism defined as?

  All chemical processes in a living organism
• What are the two types of respiration mentioned?

  Aerobic and anaerobic respiration
• When does aerobic respiration occur?

  When there is enough oxygen
• Why is aerobic respiration considered more efficient?

  It transfers more energy from glucose
• Where does aerobic respiration take place in cells?

  In mitochondria
• What is the word equation for aerobic respiration?

  Glucose + oxygen → carbon dioxide + water
• How does the chemical equation for aerobic respiration compare to photosynthesis?

  It is the exact opposite of photosynthesis
• What is anaerobic respiration?

  Respiration without oxygen
• When do humans typically rely on anaerobic respiration?

  During intense exercise when oxygen is low
• What is the word equation for anaerobic respiration in humans?

  Glucose → lactic acid
• Why is anaerobic respiration considered inefficient?

  It leads to incomplete glucose breakdown
• What happens to lactic acid after anaerobic respiration?

  It must be removed later
• How does anaerobic respiration differ in plants and yeast?

  It produces ethanol and carbon dioxide
• What is the process called when yeast undergoes anaerobic respiration?

  Fermentation
• How is fermentation used in the industry?

  To make bread, beer, and wine
• What are the key differences between aerobic and anaerobic respiration?

  • Aerobic respiration requires oxygen; anaerobic does not.
  • Aerobic produces carbon dioxide and water; anaerobic produces lactic acid or ethanol.
  • Aerobic is more efficient than anaerobic.
• What are the roles of energy in living organisms?

  • Building larger molecules (e.g., proteins)
  • Muscular contraction for movement
  • Maintaining body temperature
