Cellular respiration is the process by which the chemical energy of the molecules "food" was released and gained a part in the form of ATP. Carbohydrates, fats, and proteins can all be used as a fuel in cellular respiration, but the most common way is used as an example to examine the reactions and pathways involved.In glycolysis, glucose, carbon, 6 lines are divided into two molecules of 3-carbon molecules called pyruvate. This change was accompanied by a net increase of 2 ATP and 2 NADH molecules.Citric acid cycle (or Citric Acid) occurs in the mitochondrial matrix and create a pool of chemical energy (ATP, NADH and FADH 2) from oxidation of Pyruvate, the final product of glycolysis. Pyruvate is transported into the mitochondria and the loss of carbon dioxide to form the reductive acetyl-CoA-CoA, a 2-carbon molecule. When the reductive acetyl-CoA-CoA is oxidized to carbon dioxide in the citric acid cycle, chemical energy is released and is captured in the form of NADH and FADH 2, and ATP.Electron transport chain allows release of large amount of chemical energy stored in the reduction of NAD + (NADH) and reduce the FAD (FADH). The energy released is captured in the form of ATP (3 ATP per NADH and 2 ATP per FADH 2). Electron transport chain (ETC) consists of a series of molecules, primarily proteins, embedded in the inner mitochondrial membrane.Sugar in the need for cellular respiration is produced by plants. Animals go through a process called photosynthesis. Optics can be considered the opposite process of cellular respiration. Through a process called the light reaction and dark reaction, plants have the ability to absorb and use the energy in sunlight. This energy is then converted to water and carbon dioxide from the atmosphere into glucose and oxygen. Since this is the opposite process of cellular respiration, plants and animals are said to have a symbiotic relationship. This means the plants and animals living together and benefit from each other. When human and animal breath, they brought in oxygen and give out carbon dioxide. This carbon dioxide is made by plants and given oxygen through photosynthesis. It is a State of balance of oxygen and carbon dioxide created between animals and plants. Without one, the other would not survive in the long run.
