Storage granules are an important component of cellular metabolism in cells of the bacterial, eukaryal and archaeal domains, according to a 2011 article written by Toso et al. in Environmental Microbiology. These granules are the parts of the cell that store the cell's energy reserves. Toso et al. also note that the analysis of storage granule's organization inside the cell is lacking.Continue Reading
Storage granules facilitate metabolism by fueling the metabolic process. Metabolism is the result of the chemical reactions that take place within each cell of a living organism, and it provides energy for the important processes involved in synthesizing new organic material, according to Encyclopaedia Britannica.
Storage granules are polyphosphate bodies that contain a large amount of phosphorous and oxygen. They also have increased levels of iron and magnesium. Toso et al. describes these granules as being asymmetric to their radial locations in relation to the cylindrical axis and uniform place at the cell's ends. The positioning of the location is temporary and designed for the collection of polyphosphate into the storage granules. This positioning facilitates motility and division.
Storage granules are believed to house the cell's food reserves, explains Biology-Online.org. The storage granules hold the cell's reserve of glycogen or another carbohydrate polymer.Learn more about Cells
Eukaryotic cells are advanced cells that have, at minimum, a cellular membrane surrounding cytoplasm, a cytoskeleton and membrane-covered organelles. More advanced eukaryotic cells also contain a nucleus that protects genetic material.Full Answer >
Prokaryotic cells are single cells that evolved before eukaryotes, which are organisms whose cells contain nuclei and organelles. A prokaryotic cell has no true nucleus or membrane-bound structures called organelles. Prokaryotic cells are usually bacterial species.Full Answer >
A composite cell is any one of a collection of different types of cells that all have the same general chemical makeup that perform the same functions. Because many cells are very similar to one another in these ways, it is possible to generalize them all as composite cells.Full Answer >
RNA is important to cells because it relays information encoded in DNA to tiny organs within the cell, called ribosomes, which produce protein according to the RNA's instructions. RNA is thus vital to the basic functioning of the cell.Full Answer >
