Which of the following statements does NOT apply to the K value in the equation for the oxygen binding curve of myoglobin?It is numerically equal to p50.O A.It is defined as that oxygen partial pressure at which half of the oxygen binding sites are occupied.В.If Y> K, then myoglobin is less than 50% saturated with oxygen.OC.O D. It is a measure of the affinity of myoglobin for oxygen.OE. It is the value of po2 at which Y = 0.5.

what is main difference between myoglobin and hemogloin and in what situations/circumstancees are each used and why?
1. In oxidized meat, the meat loses oxygen and is oxidized to Fe3+. According to the data, after the oxidizing agent (K6[FeCN6]) was added, the absorption of oxidized metmyoglobin was recorded as 0.76 which is higher than oxy-Myoglobin 0.120. What does this indicates???? what does it means????? 2.However, when reducing reagent was added, the absorption of oxymyoglobin is 0.783 which is higher than 0.100 of metmyoglobin.Why is this significant? 3.can this data help to indicates that oxymyoglobin preferred bright red color. Metmyoglobin prefered brown color, and is more susceptible than oxymyoglobin to oxidation?
Which of the following are TRUE, regarding patterns of Oxygen Consumption in horses traveling at different speeds, based of the following data: A Walk o Trot • Gallop 100 - Gallop 16 12 Trot Walk 2 3 4 6 2 3 4 Running speed (ms-) Running speed (ms-) When horses trot, metabolic Cost of Transport is independent of speed. OAt the optimum speeds within each gate, metabolic Cost of Transport is independent of speed. These data show that Horses have specific adaptations for walking, trotting, and galloping. Metabolic Rate is constant, regardless of speed To travel a distance of 10 miles, it is most energetically efficient for a horse to walk. Metabolic Cost of Transport increases with increases in running speed. Rate of oxygen consumption (ml 02s) Millilitres of oxygen consumed to move
Why does release of BPG in the blood system help counter the effects of high altitude induced hypoxia? O BPG binds each hemoglobin tetramer and leads to formation of a confirmation that binds 02 more strongly allowing uptake of 02 in the lungs BPG binds myoglobin and leads to formation of a confirmation that binds 02 more strongly allowing uptake of O2 in the lungs BPG binds myoglobin and leads to formation of a confirmation that binds 02 more weakly allowing release of 02 in oxygen starved tissues O BPG binds each hemoglobin tetramer and leads to formation of a confirmation that binds 02 more weakly allowing release of 02 in oxygen starved tissues
1. Is this statement correct or incorrect? Explain. During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungs. 2. Is this statement correct or incorrect? Explain. Compared to hemoglobin, myoglobin has a lower binding affinity for O2 and a higher O2 binding capacity, two characteristics that allow myoglobin to efficiently provide skeletal muscle cells with a readily-accessible reservoir of O2.
One of your friends has anemia. They consistently complain of higher levels of fatigue when you go for runs or exercise. What is the cause of this? Decreased oxygen carrying capacity of myoglobin Decreased muscle spindle activation of the gastroc Increased use of fast twitch muscle fibers Decreased oxygen carrying capacity of hemoglobin
In sickle cell disease: O poor oxygen binding causes deformation of red blood cells a mutation in the B-chain of hemoglobin causes hemoglobin to polymerize into fibres that distort red blood cells. O the oxygen binding curve of hemoglobin must be shifted to the left hemoglobin is no longer able to bind oxygen myoglobin is not longer able to bind BPG.
How is CO2 diffusing out of working muscle transported in the blood (to the lung capillaries)? Choose the two main forms. (pKa of H2CO3: 6.4; pH of blood: 7.4) O H2CO3; CO2 gas O HCO;1: CO2 gas O HCO31; Carbamate (R-NH-Coo, CO, is carried by hemoglobin) O H,CO3; Carbamate (R-NH-COO, CO2 is carried by hemoglobin)
As the value of p50 myoglobin for oxygen rises, it falls, rises, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls, falls None of the aforementioned have a K _—- value, resulting in a strong affinity.
In the absence of 2,3-bisphosphoglycerate, the binding of oxygen by hemoglobin: a. is characterized by cooperativity b. resembles that of myoglobin c. binds at the end of the hemoglobin molecule d. is stabilized as the deoxy conformation of hemoglobin for the release into capillaries
