- To break down glucose and store the energy in ATP
- To produce water and carbon dioxide as waste products
- To provide energy for cellular activities through the breakdown of organic substances (correct)
Which of the following statements about the three stages of cellular respiration is false?
Which of the following statements about the three stages of cellular respiration is false?
- Glycolysis occurs in the cytoplasm of cells and can happen with or without the presence of oxygen
- The Krebs cycle takes place in the mitochondria and produces a small amount of ATP
- The electron transport chain is the final stage of cellular respiration and produces the majority of the cell's ATP
