Purpose of Cellular Respiration

To release energy from glucose by producing ATP in mitochondria.

Cellular Respiration Formula

Glucose + Oxygen → Carbon Dioxide + Water + ATP; translates energy from food.

Study Notes

Cellular Respiration Summary

  • The purpose of cellular respiration is to release energy from glucose to make ATP.
  • All living organisms perform cellular respiration.
  • Cellular respiration takes place in the mitochondria.
  • The process of cellular respiration involves breaking down glucose to create energy.
  • Energy is stored in chemical bonds in food molecules like glucose.
  • Glucose is the main energy source for cells.

Cell Organelles and Body Systems

  • Digestive System: Breaks down food into smaller molecules, such as glucose.
  • Respiratory System: Takes in oxygen, which is used in cellular respiration.
  • Circulatory System: Transports glucose and oxygen to cells and removes carbon dioxide and water.
  • Mitochondria: The site of cellular respiration, where ATP is produced.
  • Cytoplasm: The site where glucose is broken down into smaller molecules.
  • Nucleus: Tells the cell when to perform cellular respiration.
  • Cell Membrane: Controls what enters and exits the cell.

Cellular Respiration Formula

  • Reactants: Glucose (C6H12O6) and Oxygen (O2)
  • Products: Carbon Dioxide (CO2), Water (H2O), and ATP (energy).
