Question
Map An effective respiratory carrier must be able to pick up oxygen from the lungs and deliver it to the peripheral tissues. Oxygen-binding curves for hypothetical oxygen-carrying proteins A and B are shown i the figure below Choose any and all of the below statements that are true Protein B is not a suitable carrier because it picks up very little oxygen in the lungs 1.0 The oxygen-binding curve of an ideal carrier protein would be to the right of curve A. Proteins A and B are both unsuitable because their binding curves are sigmoidal Protein A is not a suitable carrier because it picks up very little oxygen in the lungs Proteins A and B are both suitable 15 The oxygen-binding curve of an ideal carrier protein would be between curves A and B Protein B is not a suitable carrier because its affinity·for oxygen is too high and it therefore will not deliver much oxygen to the tissues Protein A is not a suitable carrier because its affinity for oxygen is too high and it therefore wil not deliver much oxygen to the tissues The oxvgen-binding curve of an ideal carrier protein would be to the left of curve A. pO2 p02 In tissues In lungsExplanation / Answer
the second last statement (that is protein A is not a suitable carrier because its affinity for oygen is too high...) shoulad also be correct according to me other than the already ticked options.
