Respiration

• What is the main topic of the video?

  Respiration
• What is respiration primarily used for in organisms?

  To release energy from glucose
• What type of reaction is cellular respiration?

  Exothermic reaction
• What does cellular respiration involve?

  Breaking apart glucose molecules
• What is the key point about energy in respiration?

  Energy is transferred, not created
• What does the term "exothermic" mean?

  Reaction releases energy
• What are the two types of respiration?

  Aerobic and anaerobic respiration
• When does aerobic respiration occur?

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

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

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

  Glucose + oxygen → carbon dioxide + water
• What is the chemical formula for glucose?

  C$_6$H$_{12}$O$_6$
• What is anaerobic respiration?

  Respiration without oxygen
• When do humans perform anaerobic respiration?

  When sprinting and oxygen is low
• What is the word equation for anaerobic respiration in humans?

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

  Glucose is only partially broken down
• What is a toxic byproduct of anaerobic respiration?

  Lactic acid
• What is the word equation for anaerobic respiration in plants and yeast?

  Glucose → ethanol + carbon dioxide
• What is fermentation in yeast used for?

  To produce carbon dioxide and ethanol
• How is fermentation utilized in industry?

  • Yeast added to bread for air pockets
  • Yeast used to make beer and wine
