A large proportion of oxygen is left unused the human blood even after its uptake by the body tissue. This O_(2)

A large proportion of oxygen remain unused in the human blood even after its uptake by the body tissues. This O_(2)

Oxygen is of vital importance for all of us . Oxygen enters the body via the lungs and is transported to the tissues in our body by blood . There it can deliver energy by the oxidation of sugars. C_(6)H_(12)O_(6) + 6O_(2) rarr 6CO_(2) + 6H_(2)O This reaction releases 400 KJ of energy per mole of oxygen O_(2) uptake by blood is at four heme (Hm) group in this protein hemoglobin (Hb). Free Hm consists of an Fe^(2+) giving HmO_(2) complex. Carbon monoxides can be complexed similarily giving a Hm CO complex . CO is poison as it bonds more strongly to Hm than O_(2) does. The equilibrium constant K_(f) for the reaction: Hm+ CO hArr HCO " "........(i) is 1000 times larger than the equilibrium constant K_(2) for the reaction: Hm + CO_(2) hArr HmO_(2)" " ........(ii) Each Hb molecules can take up four molecules of O_(2) absorbs a fraction of this amount, depending on the oxygen pressure , as shown in figure1 (curve 1) . Also shown are the curve (2) and (3) for blood with two kinds of dificient Hb . These occur in patients with certain hereditary diseases. Relevant data , O_(2) pressure in lungs is 15 KPa , in the muscles it is 2KPa . The maximum flow of blood through heart and lungs is 4 xx 10^(-4)m^(-3)s^(-1) . The red cells in blood occupy 40% of the volume, inside the cells the concentration of Hb has a molar mass of 64 kg "mol"^(-1) R=8.314 J "mol"^(-1) K^(-1) , T=298k . Using the relation between K and the standard Gibbs energy DeltaG^(@) for a reaction, calculated the difference between the DeltaG^(@) values for the home reactions (i) and (ii).

Haemoblobin is a Fe containing protein responsible for oxygen transport in the blood. The curves given below indicate the percentage suturation of haemoglobin by O_(2) as a funcion of partial pressure of O_(2) . Which of the following statement/s is/are correct for the given curves? I. In presence of CO_(2) , higher P_(O_(2)) is needed for a given percentage saturation. II. In presence of CO_(2) , lower P_(O_(2)) is needed for a give percentage saturation. III. The maximum percentgae saturation is not affected by the presence of CO_(2) IV. In the absence of CO_(2) , maximum saturation of haemoglobin occurs at lower p_(O_(2)) .

In the given figure F=10N, R=1m , mass of the body is 2kg and moment of inertia of the body about an axis passing through O and perpendicular to the plane of the body is 4kgm^(2) . O is the centre of mass of the body. If the ground is smooth, what is the total kinetic energy of the body after 2s ?

The human ciculatory system can be thought of as a closed system of interconnecting pipes through which fluid is continuously circulated by two pumps the two pumps the right and left verticles of the heart, work as simple two-stroke force pumps. The muscles of the heart regulate the force by contracting and relaxing. the contraction (systole) lasts about 0.2s and a complete systole/diastole (contraction/relaxation) cycle lasts about 0.8s. For flood pressures and speeds in the normal range. the volume flow rate of blood through a blood vessel is directly proportional tot he pressure difference over a length of the vessel and to the fourth power of the radius of the vessel. The total mechanical energy per unit volume of blood just as it leaves the heart is E//V=rhogh+P+rhov^(2) Q. Which of the following is a way to achieve approximately a 45% increase in the volume flow rate of blood through a blood vessel?

The total mechanical energy per unit volume of blood just as it leaves the heart is E//V=rhogh+P+rhov^(2) Q. Why is diastolic blood pressure muchh lower than systolic pressure? A. because the heart exerts more force on the blood during diastole B. Because the heart exerts no force on the blood during diastole C. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same. D. Because the radii of the blood vessels increase during diastole while the force exerted by the heart on the blood remains the same.
