Cellular respiration occurs in all cells, including plant cells. The procedure involves breaking the energy stored in a usable food assimilate the cells. Through photosynthesis plants produce glucose – a simple sugar – from water, sunlight and carbon dioxide. Glucose is a stored energy, the individual cells can be used in a food they convert to fuel their metabolic processes.
Adenosine triphosphate, or ATP, the food is of all living cells, using vegetable or animal. In plant cell respiration is the process of tearing apart individual glucose molecules, and assembling of the atoms in molecules of ATP. The process involves a series of complex chemical reactions that any time the cell needs to occur to consume foods.
Glycosis, which takes place without the presence of oxygen, is the initial phase of the reactions that convert glucose into ATP. Glycosis occurs in a cell cytoplasm, a gel-like material that fills the cell. Reactions occur ten steps, each triggered by a different enzyme. Some glucose is converted into ATP during glycosis, but the process itself also uses some of the cell ATP. The net gain is two molecules of ATP per glucose molecule. Furthermore, other substances in the preparation for the second phase of respiration can be created.
Aerobic respiration of the second part of the process and more complicated, and requires the presence of oxygen for the reactions that take place during this phase. Mitochondria, tiny organelles that float in the cytoplasm, are responsible for carrying out these reactions. During aerobic respiration, the substances created during glycosis be degraded by enzymes, and the cell requires additional ATP from the resulting atoms.
Chemically, photosynthesis and cellular respiration opposing reactions. During photosynthesis, unusable solar energy is combined with carbon dioxide and water to make glucose, which is a useful, storable, chemical energy for plants. Cellular respiration breaks the warehoused glucose ATP, a different type of chemical energy, which can be immediately used by the cells to create. Water and carbon dioxide are emitted as byproducts of cellular respiration, with some of the byproducts produce recycled more glucose. Both photosynthesis and cellular respiration must occur for the plant's survival.
