The statements about hemoglobin that are true are the following:
d. Oxyhemoglobin (that is, hemoglobin bound to oxygen) and deoxyhemoglobin differ markedly in quaternary structure.
Explanation:
The structure of deoxyhemoglobin called T state, on the other side oxyhemoglobin is called R state. And these characteristics make it easier to pass from one to the other because the process is an interaction between the 1b1 and the 2b2 dimers that make them rotate and bind strongly. If those structures and natures wouldn't exist, they wouldn't be able to change from one to the other. But is because they are different that they can.
