aerobic/anaerobic 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
• Why is it incorrect to say energy is created during respiration?

  Energy is transferred, not created
• What is aerobic respiration?

  Respiration with enough oxygen
• Where does aerobic respiration occur in cells?

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

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

  C₆H₁₂O₆
• What is anaerobic respiration?

  Respiration without oxygen
• When do humans perform anaerobic respiration?

  When sprinting and oxygen is insufficient
• 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 yeast used in the bread-making process?

  It produces carbon dioxide for air pockets
• How is yeast utilized in the production of alcoholic beverages?

  It produces ethanol during fermentation
• What are the two types of respiration?

  • Aerobic respiration
  • Anaerobic respiration
• What are the key points about aerobic respiration?

  • Requires oxygen
  • Most efficient energy transfer
  • Occurs in mitochondria
• What are the key points about anaerobic respiration?

  • Occurs without oxygen
  • Less efficient energy transfer
  • Produces lactic acid in humans
  • Produces ethanol and carbon dioxide in yeast
• What are the practical applications of fermentation?

  • Bread making (carbon dioxide for fluffiness)
  • Alcohol production (ethanol for beverages)
