What is cell control?
cell control is a wide term used to describe many processes that occur in a cell aimed at maintaining homeostasis. Homeostasis is a balanced state in which the cell avoids harmful extremes of any form through various active or passive regulatory processes. Cell control processes alleviate everything from the growth and replication of cells to salt level and the acidity of the cellular environment. If the growth and replication of cells is not alleviated, cells may replicate at uncontrollably high speed; This is called cancer.
There is a large amount of cellular regulation at the genetic level. Many different genes are expressed or suppressed in response to environmental triggers to maintain the homeostasis of the cell. Various proteins are able to bind to certain RNA or DNA segments that contain genetic information used in gene expression to suppress, induce or improve the expression of the gene. Genes are an expressive protein production. e. For example ColI expresses another set of genes by producing an abnormal set of proteins when exposed to high thermal levels; These proteins make it better to maintain some form of homeostasis in the case of "thermal shock".
cell signaling is a very important aspect of cell control study, since most regulatory processes in the cell are a reaction to some signal form. Changes in cell environment may cause signal proteins or chemicals to bind to signal receptors to indicate the need for some forms of regulatory reaction. Cells even communicate with other cells to prepare them for changes in the cellular environment. Communication that results in cell control may occur in a cell, between neighboring or touch cells or even between distant cells. For example, endocrine cells are specificized cells that send chemical signals to different parts of the body to communicate the needvarious actions of cell control.
Many different diseases and disorders are due to the disintegration of cell control processes. Cancer is caused when the growth and replication of the cells are not properly regulated. Normal cells are subject to apoptosis or programmed cellular death; Cancer cells do not, so they can replicate and grow indefinitely. Autoimmune disorders are also the result of unsuccessful control and cell signaling. Such disorders occur when the immune system cannot recognize the cell as the "I" and starts an inappropriate immune attack on a harmless cell or cells.
