The textbook truth is that the only obvious function of mature red cells in the body's economy is to transport oxygen (why it is advantageous to have haemoglobin within a membrane-bounded space rather than in f
17K As an inherited disorder commonly found in individuals of African descent, sickle cell anemia affects red blood cells, making them abnormally sickle-shaped, which results in a blockage of blood flow. Learn more about sickle cell anemia, including the affected locations of the body and the si...

In your bloodstream, chloramines denaturehaemoglobin, causinghaemolytic anemia –a disorder in which red blood cells are destroyed faster than they can be made. If you are drinking as little as .5ppm, you are in the red zone. Even so, chloramines are not officially regarded as a drinking w...
Given below is the representation of amino acid composition of the relevant translated portion of β-chain of haemoglobin, related to the shape of human red blood cells. (a) Is this representation indicating a normal human or a sufferer from certain related genetic disease? Give reason in supp...
Blood Salinity Haemoglobin Terrestrial vertebrates “have body fluids roughly the same osmotic concentration as fresh-water fish, roughly 1/3 the concentration of sea water.” Endosymbiotic Theory Endosymbiosis There is strong evidence that Mitochondria and plastids were once bacteria that evolved on their...
It is taking care of these things that are non-self cells. Cancer cells basically get controlled by the immune system until it cannot do it anymore, and then we get a cancer diagnosis. Because the cells have exceeded our immune system’s ability to handle them and they form something, ...
Describe the structure, quantity and function of haemoglobin. What happens to globin and heme when RBCs are destroyed? Why do red blood cells have a finite life-span? Describe some of the causes of anemia. Why is anemia dangerous? What are the important roles of the heme groups within each...
