Red Blood Cells -- Mitochondria, Nucleus, Atp

I was watching Law and Order one lousiness and the topic was falsifying DNA evidence. During the show they mentioned that cherry- deprivation line of descent cells do not build mitochondria or nuclei. The bad guys took wages of this fact to ferment a inventory sample with redness business cells that would contain only the DNA they added from the cop they view to frame. I was very surprised by the accuracy of this scenario! This is a re wholey cool thing astir(predicate) red seam cells, because when we talk about eukaryotic cells we say they have a core group and other complex organelles -- like mitochondria, just now red assembly line cells are different. The main percentage of red blood cells is to carry oxygen. To do this they contain a special protein tittle called haemoglobin. Hemoglobin binds to both oxygen and carbon copy dioxide. It carries oxygen to cells that rent it and picks up the carbon dioxide that is a use product of aerophilous resp iration and returns that to the lungs to be exhaled. In decree for this process to be very efficient, red blood cells have no pith -- it would take up too often room. You should hence ask, since the nucleus contains the DNA and this is required for cell stratum and the production of proteins, accordingly how do these cells divide and grow? The candid answer is, they dont! sanguine blood cells come from bone core cells.

Bone marrow cells grow and divide. When the bone marrow cells get along with they become all of the different types of blood cells. As a red blood cell matures, it loses its nucleu s. No nucleus, no DNA, no cell division. ro! sy blood cells live only about 120 days, then the die. Now maybe you would wonder how red blood cells make much haemoglobin if there is no DNA to enounce them how. They do not do that either. near all of the hemoglobin they need is made before they mature. A little remnant ER allows some final hemoglobin synthesis, but the ER disappears too to make room for more hemoglobin. Red blood cells do not have mitochondria either. call in about it.
