3. What happened when the cell growth is not regulated?
Explanation:
What genes control the growth of cell growth? What is the purpose of this regulation? What happened when the cell growth is not regulated?
Above are the questions which an observe would ask about regulation of cell growth. A number of genes such as oncogenes and tumor suppressor genes are involved in the regulation of cell growth and cell division. Regulation of cell growth process ensures that a cell's DNA which is dividing is copied properly as well as repair errors in the DNA. It also ensures that each daughter cell receives a complete set of chromosomes in order to gain healthy daughter cells.
<span>Norepinephrine uses the Second
Messenger System, which means, cells signal to each other what molecules have
been released that will trigger a physiological reaction. </span>
<span>
This phenomenon is activated after the ligand (ion or molecule) is bonded to its receptor
(protein molecule), creating a variation that causes a chain-reaction, that will
finally activate the Second Messenger. The latter will activate intercellular
molecules that will be able to control the cell’s activity. </span>
