8.9 - Cellular Respiration and 8.10 - Anaerobic and Aerobic Respiration Flashcards
What is respiration?
Respiration is the process of transferring energy from glucose so living processes can occur.
Is respiration exothermic or endothermic?
Respiration is exothermic as energy is transferred to the environment.
What are the two types of respiration?
Respiration can take place aerobically (with oxygen) or anaerobically (without oxygen).
What is required for aerobic respiration?
Aerobic respiration requires oxygen.
What is the energy yield of aerobic respiration?
Aerobic respiration produces a large amount of energy (high yield).
Where does aerobic respiration occur?
Aerobic respiration takes place in the mitochondria of cells.
When does aerobic respiration occur?
Aerobic respiration happens all the time in most cells.
What are the reactants of aerobic respiration?
The reactants are glucose (C₆H₁₂O₆) and oxygen (O₂).
What are the products of aerobic respiration in animals?
The products are carbon dioxide (CO₂) and water (H₂O).
What are the products of aerobic respiration in yeast/plants?
The products are carbon dioxide (CO₂) and water (H₂O).
What is the equation for aerobic respiration in words?
Glucose + Oxygen → Carbon dioxide + Water
What is the equation for aerobic respiration in symbols?
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
What is required for anaerobic respiration?
Anaerobic respiration does not require oxygen.
What is the energy yield of anaerobic respiration?
Anaerobic respiration produces less energy (low yield).
Where does anaerobic respiration occur?
Anaerobic respiration takes place in the cytoplasm of cells.
When does anaerobic respiration occur?
Anaerobic respiration happens when oxygen is limited, e.g., during vigorous exercise.
What are the reactants of anaerobic respiration?
The reactants are glucose (C₆H₁₂O₆) only.
What are the products of anaerobic respiration in animals?
The product is lactic acid.
What are the products of anaerobic respiration in yeast/plants?
The products are ethanol and carbon dioxide (CO₂).
What is the equation for anaerobic respiration in animals in words?
Glucose → Lactic acid
What is the equation for anaerobic respiration in yeast/plants in words?
Glucose → Ethanol + Carbon dioxide (CO₂)
What is the equation for anaerobic respiration in symbols for animals?
C₆H₁₂O₆ → 2C₃H₆O₃ (Lactic acid)
What is the equation for anaerobic respiration in symbols for yeast/plants?
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ (Fermentation)
What are the uses of aerobic respiration?
Aerobic respiration is used for everyday energy needs, e.g., walking, breathing, growing.
