Cellular Respiration

The video explains the importance of energy for powering homes and living organisms. It introduces cellular respiration as the body's power plant, converting food into energy in the form of ATP and NADH. The process occurs in the mitochondria and is more efficient than a gasoline engine. Digestion breaks down food, which fuels cellular respiration, turning glucose into carbon dioxide, water, and energy compounds. The video highlights the efficiency of cellular respiration compared to engines.

What is the primary function of cellular respiration in living organisms?

• To break down food into energy

• To generate oxygen for cells

• To store energy in the form of fat

• To produce glucose from carbon dioxide

Which molecules are primarily produced during cellular respiration to provide energy for cells?

• ATP and NADH

• Proteins and lipids

• Carbon dioxide and water

• Glucose and oxygen

Where does cellular respiration occur within eukaryotic cells?

• In the chloroplasts

• In the mitochondria

• In the ribosomes

• In the nucleus

How does the efficiency of cellular respiration compare to that of a gasoline engine?

• Cells are less efficient than engines

• Cells are equally efficient as engines

• Cells are more efficient than engines

• Cells do not use food as fuel

What is the role of oxygen in the process of cellular respiration?

• It is stored as ATP

• It is converted into glucose

• It is used to oxidize sugars

• It is not involved in cellular respiration
