Aerobic Respiration

• What is aerobic respiration?

  Breaking down food with oxygen for energy
• What does the Krebs cycle produce as a byproduct?

  Carbon dioxide
• How does aerobic respiration affect your physical state?

  It makes you feel active and strong
• Why is aerobic respiration essential for life?

  It provides ATP for cellular functions
• What are the reactants and products of aerobic respiration?

  Reactants:

  • Glucose
  • Oxygen

  Products:

  • Carbon dioxide
  • Water
  • ATP
• Where does glycolysis occur in the cell?

  In the cytoplasm
• What are the main products of the Citric Acid Cycle?

  • 2 ATP
  • 2 NADH
  • 1 FADH2
• What does glycolysis break glucose into?

  Pyruvate
• What do the stages of aerobic respiration create for cells?

  Energy currency (ATP)
• What is the result of aerobic respiration in terms of energy?

  It releases a large amount of energy
• What are the main products of aerobic respiration?

  Carbon dioxide, water, and ATP
• What are the stages of aerobic respiration?

  Glycolysis, Link reaction, Krebs cycle, Electron transport chain
• How does the Electron Transport Chain shown in the image differ from the Citric Acid Cycle?

  The Electron Transport Chain is the final stage of cellular respiration that generates a large amount of ATP, while the Citric Acid Cycle is an earlier stage that produces NADH and FADH2 to fuel the Electron Transport Chain
• What are the two key molecules removed from the diagram linking photosynthesis and respiration in plants?

  1: oxygen, 2: carbon dioxide
• What type of combustion occurs in aerobic respiration?

  Complete
• What is the energy yield of aerobic respiration?

  High (36 - 38 ATP)
• What are the reactants and products of photosynthesis?

  Reactants:

  • Carbon dioxide
  • Water

  Products:

  • Glucose
  • Oxygen
• What is the product of anaerobic respiration in animals?

  Lactic acid
• What are the reactants of aerobic respiration?

  Glucose and oxygen
• Where does aerobic respiration occur?

  Cytoplasm and mitochondrion
• What are the reactants for aerobic respiration?

  Glucose and oxygen
• What is aerobic respiration?

  Respiration that occurs with oxygen
• What are the reactants of aerobic respiration?

  Glucose and oxygen
• What is the role of chloroplasts in photosynthesis?

  Chloroplasts are the site of photosynthesis and contain chlorophyll, the pigment that absorbs light energy.
• What are the products of anaerobic respiration in animals?

  Lactic acid
• What is produced as a result of electrons moving down the electron transport chain?

  ATP is produced
• Why is oxygen important in the electron transport chain?

  It allows electrons to move down the chain
• If a cell has a limited supply of oxygen, which type of respiration would it use to produce ATP?

  Anaerobic respiration
• What is the formula to calculate the area of a circle with radius $r$?


  $A =$$\pi r^2$
• What are the stages of aerobic respiration?

  1. Glucose and oxygen are combined
  2. The process occurs in three stages
  3. Carbon dioxide, water, and ATP are released
• Why is aerobic respiration more efficient than anaerobic respiration?

  It allows for efficient energy production
• What is the energy yield of anaerobic respiration?

  Low (2 ATP)
• How does the Citric Acid Cycle relate to the Electron Transport Chain shown in the image?

  • The Citric Acid Cycle produces NADH and FADH2, which are then used in the Electron Transport Chain to generate more ATP.
  • The Electron Transport Chain is the final stage of cellular respiration, where the energy from NADH and FADH2 is used to produce a large amount of ATP.
• Where does the electron transport chain occur?

  In the inner mitochondrial membrane
• What role does aerobic respiration play in brain function?

  It provides energy for studying and learning
• What is the role of mitochondria in respiration?

  Mitochondria are the site of aerobic respiration, where the energy from glucose is converted into ATP.
• What is the formula to calculate the area of a circle?

  $A =$$\pi r^2$
• Where does anaerobic respiration occur?

  Cytoplasm
• If the reactants of aerobic respiration are glucose and oxygen, what is the chemical equation for the overall process?

  $C_6H_{12}O_6 +$$6O_2 \rightarrow 6CO_2 +$$6H_2O +$$\text{ATP}$
• What are the key differences between aerobic and anaerobic respiration?

  • Aerobic respiration uses oxygen, anaerobic does not
  • Aerobic produces CO2 and H2O, anaerobic produces lactic acid or ethanol
  • Aerobic produces much more ATP than anaerobic
  • Aerobic is more efficient at producing energy
