Q1:

The conformational changes from the T to the R state is initiated by

A binding of oxygen to the heme

B movement of the proximal histidine towards the heme

C movement of the F-helix, which contains the proximal His

D reorganization of protein-protein contacts between the individual subunits

ANS:A - binding of oxygen to the heme

T stands for tensed state and R stands for relaxed state.
