Cellular respiration is the breaking down of organic compounds (glucose) with the gradual release of energy that is stored in ATP molecules. Oxygen is required and carbon dioxide and water are released as waste products
All living organisms of composed of cells. Cells constantly perform work and therefore require energy
Organisms use energy for the following life processes; growth, cell division, digestion, movement, transport substances in the body, active transport against a concentration gradient
Raw materials needed for cellular respiration: glucose, oxygen
Products of cellular respiration: carbon dioxide, water, ATP (energy)
Glucose + O2 ----> CO2 + H2O + ATP
Photosynthesis is an anabolic process, because energy-rich glucose is built up
Cellular respiration is a catabolic process, because energy-rich glucose is broken down
The first phase of cellular respiration takes place in the cytoplasm outside the mitochondrion, known as the cytosol
The second and third phase of cellular respiration occur inside the mitochondrion
