Practice question
Question
In an individual, three distinct proteins bind oxygen depending on the location and development stage. While hemoglobin is the major oxygen binding protein in adults, myoglobin is present in skeletal muscles and fetal hemoglobin is present in fetal stage only. The following graph shows the oxygen binding capacity of these proteins. The A, B and C plots represent oxygen binding capacity of
Explanation
In biochemistry, enzyme kinetics dictates that substrate binding and catalytic efficiency determine reaction rates. Therefore myoglobin, fetal hemoglobin and hemoglobin, respectively is correct as it reflects active-site specificity and regulation, supported by mechanistic studies and conserved across related systems.
