The phosphorylation of tyrosine residues can facilitate therecruitment of proteins with which of the following domains?

Rank the hemoglobin molecules with the described conditions frommost likely to bind oxygen molecules to most likely to releaseoxygen molecules.

hemoglobin molecules: * 1 bound O2, PO2=100mm Hg
* 3 bound O2, PO2=40mm Hg
* 1 bound O2, PO2=40mm Hg
* 3 bound O2, PO2=100mm Hg

Most likely to bind oxygen molecules Most likely to release oxygenmolecules
