IntroductionHello everyone this is a new and revamped version of our previous Slide show on cellular respiration. What is cellular respiration?The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All living cells must carry out cellular respiration. It can be aerobic respirationin the presence of oxygen oranaerobic respiration.

How does it happenCellular respiration begins in the cell's cytoplasm. There, glucose is broken down through a series of chemical reactions to produce small molecules of a substance called pyruvate. This part of the process is called glycolysis; it does not require oxygen and releases a small amount of energy, which is captured by a few ATPs. How Does it happen IIThe pyruvate molecules then enter the mitochondria, where they undergo a series of chemical reactions with oxygen. The reactions also release hydrogen, which combines with oxygen to produce water; and carbon, which combines with oxygen to produce carbon dioxide. What are the Equations?As you can see below the equations show that organisms use oxygen to break down food molecules to get chemical energy for cell functions. The water and carbon dioxide are released as waste products; the ATPs leave the mitochondria and deliver their captured energy to places in the cell where it is needed to power cellular activities.
