Erythrocytes Survive 120 Days Hemoglobin * Globin: 4 folded polypeptide chains * Heme: Iron group in each polypeptide that binds 02 Enzymes: * Glycolytic: generate energy through glycolysis due to lack of mitochondria * Carbonic anhydrase: for transport of CO2 into HCO3 Erythropoiesis: * regeneration of new cells in the bone marrow Erythropoietin (hormone): * when kidneys detect not enough 02 they secrete this hormone which stimulates erythropoiesis‚ increasing 02 capacity

SNAKE BITES VENOM AND ANTI-VENOM Snake venom is modified saliva and is produced by modified saliva glands. Venoms are rich in hydrolithic enzymes‚ a complex mix of polypeptides‚ nucleases‚ peptidases‚ etc.‚ which help digest the snake’s prey. Some of them also enhance or contribute to the toxic effect of the venom. As early as 1949 it was shown that an enzyme from the Bothrops species produces a vasodilation resulting from the production of a hypotensor neuropeptide‚ bradykinin. This had important

The Importance of Calcium Ions Alyssa Foels 12 February 2015 Kilfe Calcium is a cation‚ a positively charged atom‚ and it is essential to all living things. It was first discovered in 1808 by Humphrey Davy. When forming an ionic bond with other elements‚ calcium loses electrons to make its valence shell stable. This means that it has more protons than electrons‚ making it have a slight positive charge (Calcium). Calcium has many roles and functions in the human body. Calcium ions are the

Title Biochemical Analysis of Blood Abstract Introduction After blood is collected from a patient it is analysed to check the fragments present and the fluid which will either be plasma or serum. After plasma is separated from blood it recollects the fibrinogen which in turn helps in clotting however serum is the portion of blood which remains after the fibrinogen is removed. Serum contains approximately 6-8% of the proteins which make up blood however plasma creates up to 55% of blood

Hemophilia is an inherited medical condition where the blood does not clot properly. Hemophiliacs - people with hemophilia‚ lack a protein called a clotting factor that works with platelets to stop bleeding at the site of an injury. People with hemophilia tend to bleed for longer periods of time after an injury and they are more susceptible to internal bleeding. Excessive bleeding can occur both externally and internally. Signs of excessive external bleeding include bleeding in the mouth from
