What is the likely range of the Hill constant for the hemoglobin described in Problem 23?

Short Answer

Expert verified

The range of the hill constant for the hemoglobin discussed in Problem 23 will most likely be 1.1 鈥� 2.

Step by step solution

01

Hill constant

The Hill constant indicates the cooperativity of the hemoglobin-oxygen binding. It is commonly a measurement of the number of ligand molecules bound to a functional protein.

02

Hill constant range  

In cooperative binding, more than one subunit of a protein bind with the ligands. Hence, the Hill constant for a cooperative binding should have a value > 1.

At the same time, the hill constant should not be more than the number of the hemoglobin鈥檚 oxygen binding sites, which is 2.

Thus, in this case, the hill constant might range from 1.1 to 2.

Question: Why do antibodies raised against a native protein sometimes fail to bind to the corresponding denatured protein?

In humans, the urge to breathe results from high concentrations of CO2 in the blood; there are no direct physiological sensors of blood pO2. Skin divers often hyperventilate (breath rapidly and deeply for several minutes) just before making a dive in the belief that this will increase the O2 content of their blood. (a) Does it do so? (b) Use your knowledge of hemoglobin function to evaluate whether this practice is useful.

If myoglobin had the same p50 value as hemoglobin, how well would it facilitate O2 diffusion under the conditions described in Problem 21?

In striated muscle, cells undergo mitosis (nuclear division) without cytokinesis (cellular division), giving rise to large multinucleated cells. Explain why muscle cells would be less effective if cytokinesis occurred with every round of mitosis.

What are the roles of Ca2+ and ATP in muscle contraction?
