Cellular Respiration

What is cellular respiration?

• The process by which cells break down water to produce energy

• The process by which cells break down carbon dioxide to produce energy

• The process by which cells break down glucose and other organic molecules to produce ATP for energy.

• The process by which cells break down sunlight to produce energy

What is cellular respiration?

• The process by which cells break down glucose and other organic molecules to produce ATP for energy.

• The process by which cells break down sunlight to produce energy

What are the three main stages of cellular respiration?

• Photosynthesis, fermentation, and anaerobic respiration

• Glycolysis, the citric acid cycle, and oxidative phosphorylation

• Krebs cycle, electron transport chain, and lactic acid fermentation

• ATP synthesis, carbon fixation, and light-dependent reactions

Where does cellular respiration take place in the cell?

• Endoplasmic reticulum

• Mitochondria

• Nucleus

• Golgi apparatus

What are the reactants of cellular respiration?

• Water and carbon dioxide

• Protein and fat

• Glucose and oxygen

• Starch and nitrogen

What are the products of cellular respiration?

• Oxygen, glucose, and heat

• Nitrogen, hydrogen, and sunlight

• Protein, fat, and vitamins

• Carbon dioxide, water, and ATP

What is the role of oxygen in cellular respiration?

• Oxygen is used to produce glucose in the cytoplasm

• Oxygen is only needed for photosynthesis, not cellular respiration

• Oxygen is converted into carbon dioxide during cellular respiration

• Oxygen is used as the final electron acceptor in the electron transport chain to produce ATP.

What is the difference between aerobic and anaerobic respiration?

• Aerobic respiration takes place in the absence of glucose, while anaerobic respiration requires glucose.

• Aerobic respiration occurs in plants, while anaerobic respiration occurs in animals.

• Aerobic respiration requires oxygen, while anaerobic respiration does not.

• Aerobic respiration produces more ATP than anaerobic respiration.

How is energy released during cellular respiration?

• Through the process of breaking down glucose and other organic molecules in the presence of oxygen.

• Through the process of photosynthesis

• By consuming large amounts of water

• By absorbing sunlight directly into the cells

What is the overall chemical equation for cellular respiration?

• C6H12O6 + 6O2 → 6CO2 + 6H2O + Glucose

• H2O + CO2 → C6H12O6 + 6O2 + ATP

• 6CO2 + 6H2O + ATP → C6H12O6 + 6O2

• C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
