4.8 Three Stages of Cellular Respiration

Identify the stage of cellular respiration where glucose is split into two molecules of pyruvic acid.

• Citric acid cycle

• Calvin cycle

• Electron transport chain

• Glycolysis

Identify the stage of cellular respiration that occurs entirely outside of the mitochondria.

• Citric acid cycle

• Electron transport chain

• Glycolysis

• All of the above occur outside of the mitochondria

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

• Glycolysis

• Citric acid cycle

• Fermentation

• Electron transport chain

Which stage of cellular respiration requires oxygen that you breathe?

• Glycolysis

• Citric acid cycle

• Electron transport chain

• Both the citric acid cycle and the electron transport chain require oxygen

ATP molecules are charged during cellular respiration; where does the energy to charge the ATPs comes from?

• The energy comes from the breaking of chemical bonds within glucose.

• The energy comes from the water.

• The energy comes from the building of carbon dioxide.

• The energy comes from the breaking of oxygen.
