Does myoglobin have the same high affinity for CO as hemoglobin?
Step by step
Solved in 2 steps
- Will a decrease in elevation shift the binding curve of hemoglobin? Will it shift the curve to the left or right, shift to myoglobin or no longer bind to O2?At which temperature given does hemoglobin have a higher affinity for oxygen?does decreasing 2,3-BPG concentration increase or decrease the binding affinity of hemoglobin for oxygen?
- How does 2,3-BPG lower the oxygen affinity of hemoglobin so significantly?What is the highest level of organization in myoglobin? In hemoglobin?does BPG bind to deoxyhemoglobin only？why BPG does not bind to oxyhemoglobin？ what is chemical structure difference between deoxyhemoglobin and oxyhemoglobin？
- After spending a day or more at high altitude (with an oxygen partial pressure of 75 torr), the concentration of 2,3- bisphosphoglycerate (2,3-BPG) in red blood cells increases. What effect would an increased concentration of 2,3-BPG have on the oxygen-binding curve for hemoglobin? Why would this adaptation be beneficial for functioning well at high altitude?Will a decrease in carbon dioxide (CO2) shift the binding curve of hemoglobin? Will it shift to the left or right?Why is oxygen efficiently transferred from hemoglobin in theblood to myoglobin in the muscles?
