The Language Of The Cell :: essays research papers

The Language of The CellThe mobile phone is a complex and delicate system It can be seen that the cellis the stage where everyday functions much(prenominal) as molecule movement, proteinsynthesis and tissue repair take place. All organelles within the cell argon wellrehearsed in their operations, but an error on an organelles behalf, can sendthe cell and its organelles into panic. The efficiency rate of the cellplummets down to a low level. It does take some time for the dust to settle,and one time the scripts are memorized, the cell is now ready to begin its tasksagain.Since the 19th Century, it was known that all vivification things, whetherthey were plants or animals, were made up of cells. This whole root word has beengiven credit to an English Physicist, Robert Hook (1635-1703), when he looked ata thin slice of cork under powerful hand lens. Hook notice a large numberof cells. Rudolf Virchow (1821-1902) propounded this idea, that the cell is abasic structure and functiona l unit for all living organisms.A cell can be a wide range of shapes and sizes, although most cells aremicroscopic. Inside a cell membrane, a nucleus can be seen. The nucleus is thecontrol magnetic core of the cell. Between the nucleus and the membrane, there is apolysaccharide matrix called the cytoplasm, where organelles can be found. Theorganelles are attached to a framework. The cells cytoskeleton.Every living cell has the ability to detect signals from itsenvironment. The signals are usually in the form of chemical molecules, thatthe cell has learned to recognize. The cell decodes these molecules intomessages, and acts upon them. The cell has a manner of speaking. Signals and messagesare carried by particles of matter that have a very low energy requirements.There are many, many signals rumbling around the cell. It was thought that thecell would confuse itself in all of that background signal noise. One defenseis available to this question. The cells decoding mechanisms are l ocateddownstream from the receptors. They are based on complex chemical reactionsthat take place in the cell membrane and control all the responses of the cellto the messages it receives.Neuropeptides and polypeptide hormones, are made up of complexassemblies of amino acids, aligned in different sequences. In other cases, theamino acids are slightly transformed, as this is the case with well known transmitter substances such as epinephrine (adrenaline), dopamine and histamine.Products made in the organelles within the cell, are sent to variousdestinations, both in and out of the cell. The cell has what amounts to a
