Co2 dissociates from carbaminohaemoglobin when

The carbonic acid then dissociates to form a bicarbonate ion and a proton (H+). (High partial pressures of Carbon dioxide is known as hypercapnea. As CO2 eventually leads to the generation of H+ in the blood, this can also cause the blood pH to fall, causing respiratory acidosis) --> so carbon dioxide present combines with water in the erythrocytes to form carbonic acid with the aid of enzyme carbonic anhydrase. This is a reversib le process. 3. Carbonic acid then dissociates into hydrogen ions and hydrogen carbonate ions.

Venous (deoxygenated) Hb has a high affinity for H+ and because of the Haldane effect this means that it can carry more CO2 as carbaminohaemoglobin How does Deoxy-Hb buffer H+ Deoxy-Hb reacts with Hb to form HHb (Haemoglobinic acid) which drives the equation towards more HCO3- ions in the blood which dissociated into CO2 -> diffuses out of membrane and gets exhaled 23% combines with the protein portion of haemoglobin and plasma proteins to form carbaminohaemoglobin. 70% transported as bicarbonate ions. As the CO 2 diffuses into the systemic capillaries it reacts with water, in the presence of carbonic anhydrase it forms carbonic acid (H 2 CO 3 ) which easily dissociates into hydrogen (H + ) and Blood transports CO 2 from the tissue cells to the lungs in three ways:. 1. Dissolved in plasma : About 7 – 10% of CO 2 is transported in a dissolved form in the plasma. 2.

Transported in 3 ways:-5% dissolved in blood plasma (pC02) 20% combined with haemoglobin carbaminohaemoglobin. 60-80% combines with water to form bicarbonate in plasma. Forms carbonic acid. (c). As bicarbonates: About 70% of CO 2 is transported as bicarbonates. Initially, in the RBC potassium haemoglobin dissociates into K + + Hb.CO 2 when diffuses in the RBC combines with water of the cytoplasm to form carbonic acid which dissociates into H + and HCO 3-ions. Haemoglobin combine with H + ions to form haemoglobin acid. While in the plasma same CO 2 combines worth water of the Haemoglobin forms carbaminohaemoglobin with CO 2. This occurs more readily for deoxygenated than oxygenated haemoglobin, contributing to the Haldane effect. Carbamino compounds account for 30% of CO 2 carriage. Dissolved carbon dioxide. CO2 is 20 times more soluble than O2 in plasma, and ∼10% of CO2 in blood is carried in solution. Carbon dioxide is waste product. It must be excreted out from the body. Carbon dioxide is carried by the blood from the tissues to the lungs in three forms. 1.

CO2 is produced in aerobic respiration It diffuses from cells to tissue fluid to blood plasma 85% of Co2 is transported as hydrogen carbonate ions in the blood plasma 10% of CO2 is transported as carbaminohaemoglobin in the red blood cells 5% CO2 is transported as dissolved CO2 in … The amount of CO2 held in the carbamino form is small but accounts for a third difference in the carbon dioxide content in veins and arteries. When blood reaches the lungs, it freely dissociates from the haemoglobin and is expelled from the body. Dissolving in blood plasma Carbon dioxide dissolves in blood plasma; it is more soluble than oxygen Essay on Transportation of Gases in Blood! (I) Oxygen Transport: Each decilitre of blood carries 19.8 ml of O2 of which 4.6 ml diffuses into tissues. 3% is transported dissolved in plasma because water has poor solubility for O2. Hence, blood plasma is a poor carrier of this gas and 97% is carried by RBCs. Carbon dioxide is produced by the tissues and diffuses into the plasma. In the plasma:... The carbonic acid dissociates and the hydrogen ion combines with the reduced haemoglobin and the bicarbonate diffuses out of the cell... (carbaminohaemoglobin) production of this compound is increased in conditions of hypoxia and reduced when the

It can dissolve directly into the blood plasma it can combine with haemoglobin to form a compound known as carbaminohaemoglobin it can form hydrogen carbonate ions The majority of carbon dioxide (around 85%) is transported in the latter way. This is a fairly complicated process When carbon dioxide binds to hemoglobin, a molecule called carbaminohemoglobin is formed. Binding of carbon dioxide to hemoglobin is reversible. Therefore, when it reaches the lungs, the carbon dioxide can freely dissociate from the hemoglobin and be expelled from the body. At the lungs, the haemoglobinic acid dissociates to form haemoglobin and H+, and the NaHCO 3 dissociates to form NA+ and HCO 3-. The sodium ions remain in the blood and can be reused in the body. The HCO 3-recombines with the H+ from the haemoglobinic acid to form H 2 CO 3, which dissociates again into water and CO 2. The CO 2 diffuses into the Carbaminohaemoglobin dissociates to form CO 2 and Hb. Hb then picks up O 2, and HHb (haemoglobinic acid) dissociates to form H + and Hb. The H+ ions combine with HCO 3-to form carbonic acid, which dissociates to form CO 2 and water (catalysed by carbonic anhydrase). CO 2 diffuses into alveoli. The presence of a high pCO 2 causes Hb to release

• The carbonic acid then dissociates into water and CO2 and the CO2 diffuses towards the alveoli. Associated with this movement of hydrogen ions into the erythrocytes is a slight increase in blood pH and an associated increase in the uptake of oxygen by the Hb Blood carries oxygen, carbon dioxide, and hydrogen ions between tissues and the lungs. The majority of CO2 transported in the blood is dissolved in plasma (primarily as dissolved bicarbonate ; 60%). Carbon dioxide combines with water and forms carbonic acid. Since the process of forming carbonic acid is slow, only a small amount of carbon dioxide is carried this way. (2) Through RBCs: About 20 – 25% of CO 2 is transported by the red blood cells as carbaminohaemoglobin. Carbon dioxide binds to the amino groups on the polypeptide chains of Carbaminohemoglobin (or carbaminohaemoglobin, also known as carbhaemoglobin and carbohaemoglobin) is a compound of hemoglobin and carbon dioxide, and is one of the forms in which carbon dioxide exists in the blood. 10% of carbon dioxide is carried in blood this way (85% carried in blood as bicarbonate [hydrogen carbonate], 5% to 7% carried as free CO2, in solution, or plasma).
