Cellular Respiration Concepts

The video explains the difference between breathing and cellular respiration. Breathing is part of the respiratory system, while cellular respiration occurs in cells using oxygen to process glucose, producing ATP, water, and carbon dioxide. ATP is crucial for cellular functions. The video also covers aerobic and anaerobic respiration, highlighting how cells adapt when oxygen is scarce, such as during intense exercise.

What is the primary function of the respiratory system?

• To produce energy

• To circulate blood

• To deliver oxygen to cells

• To digest food

What is the main purpose of cellular respiration?

• To break down proteins

• To produce glucose

• To generate energy for cells

• To store fat

Which molecule is known as the energy currency of the cell?

• RNA

• Glucose

• DNA

• ATP

What happens to carbon dioxide produced during cellular respiration?

• It is stored in the cells

• It is converted into glucose

• It is expelled from the body

• It is used to build proteins

Which of the following is NOT a byproduct of cellular respiration?

• ATP

• Oxygen

• Carbon dioxide

• Water

Cellular respiration occurs in which part of the cell?

• Nucleus

• Cytoplasm

• Mitochondria

• Ribosome

What is another name for cellular respiration that uses oxygen?

• Fermentation

• Aerobic respiration

• Photosynthesis

• Anaerobic respiration

What is the backup process cells use when oxygen is scarce?

• Photosynthesis

• Glycolysis

• Fermentation

• Oxidation

Which organisms rely solely on anaerobic respiration?

• Animals

• Humans

• Plants

• Yeasts

What is the main difference between aerobic and anaerobic respiration?

• Aerobic uses glucose, anaerobic does not

• Aerobic produces carbon dioxide, anaerobic does not

• Aerobic occurs in plants, anaerobic in animals

• Aerobic requires oxygen, anaerobic does not
