These 10 animal facts will amaze you. The face of farming and agriculture has changed drastically over the past 100 years. At the beginning of the 20th century, over 70% of the population of the United States lived and worked on farms, but by 2008, the figure had dropped to less that 3%.
During this process, glucose from food is broken down into carbon dioxide and water, and energy is released. The process of releasing energy from food is called respiration, or cellular respiration as it is a series of steps that take place within living cells. It is important to not confuse respiration, or oxidizing glucose, with breathing.
The Reaction. During cellular respiration, oxygen and glucose (sugar) are transformed into carbon dioxide and water. Chemical energy in the form of adenosine triphosphate (ATP) is released during the reaction.lucose is oxidized during cellular respiration to form carbon dioxide. Oxidation releases the energy stored in the chemical bonds of the glucose molecule.
