Respiration

• What are the two types of respiration mentioned?

  Aerobic and anaerobic respiration
• Why is respiration important for energy?

  It releases energy from glucose molecules
• What is cellular respiration described as?

  An exothermic reaction
• What does the term 'exothermic' mean in respiration?

  The reaction releases energy
• What is one use of energy from respiration?

  To build larger molecules from smaller ones
• What is another use of energy from respiration?

  For muscular contraction
• How does energy help maintain body temperature?

  It keeps us warm in colder environments
• What is metabolism defined as?

  All chemical processes in a living organism
• Where does aerobic respiration take place?

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

  Glucose + oxygen → carbon dioxide + water
• What is notable about the chemical symbols in the aerobic respiration equation?

  There are six of everything except glucose
• How does the equation for aerobic respiration relate to photosynthesis?

  It is the exact opposite of photosynthesis
• When do we use anaerobic respiration?

  When we can't get enough oxygen
• What is the word equation for anaerobic respiration?

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

  Incomplete breakdown of glucose occurs
• What is a consequence of lactic acid buildup?

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

  It produces ethanol and carbon dioxide
• What is fermentation in yeast used for?

  To make bread, beer, and wine
• What are the main uses of energy from respiration?

  • Build larger molecules from smaller ones
  • Muscular contraction
  • Maintain body temperature
• What are the key differences between aerobic and anaerobic respiration?

  Aerobic Respiration:

  • Requires oxygen
  • Produces carbon dioxide and water
  • More efficient

  
  

  Anaerobic Respiration:

  • Occurs without oxygen
  • Produces lactic acid (in animals) or ethanol and carbon dioxide (in yeast)
  • Less efficient
• What is the relationship between photosynthesis and respiration?

  • Photosynthesis produces glucose
  • Respiration uses glucose to release energy
  • Equations are opposites
• What is the role of enzymes in metabolism?

  • Catalyze reactions
  • Speed up chemical processes
  • Help maintain life
• What are the products of fermentation in yeast?

  • Ethanol
  • Carbon dioxide
