Cellular Respiration

What is the purpose of cell respiration?

• produce carbon dioxide and water for energy

• produce food for the organism

• break down carbon dioxide for energy

• break down glucose for energy in the presence of oxygen

In which organelle does cellular respiration MOSTLY take place?

• mitochondria

• chloroplast

• nucleus

• vacuole

The equation shows the chemical equation for cellular respiration. Which belongs in the empty box?

• cell

• chlorophyll

• glucose

• sunlight

What would happen to the rate of cell respiration taking place in rat cells if I decrease the amount of oxygen available?

• increase

• decrease

• stay the same

Which process does this chemical formula represent?

• Photosynthesis
• Cellular Respiration

During which stage of cellular respiration is the majority of ATP produced?

• Fermentation

• Electron Transport Chain

• Krebs Cycle

• Glycolysis

Which statement best describes cellular respiration?

• It converts energy in food into a more usable form (ATP).

• It stores energy in food molecules

• It occurs in animal cells, but not in plant cells.

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

• Krebs Cycle

• Electron Transport Chain

• Calvin Cycle

• Glycolysis

How does cellular respiration differ between aerobic and anaerobic conditions?

• Both processes produce the same amount of ATP.

• Aerobic respiration occurs in the cytoplasm, while anaerobic occurs in mitochondria.

• Anaerobic respiration produces more ATP than aerobic.

• Aerobic respiration requires oxygen, while anaerobic does not.

Which molecule is broken down during glycolysis?

• Carbon Dioxide

• Water

• ATP

• Glucose
