Well I hope these steps are good:
1) First, the addiotional T state of the Hemoglobine Sinteract with the agregation that is growing to form a fiber that is insoluble.
2) Second, Val makes an interaction with a cell or pocket of a beta chain on another Hemoglonine S.
·3) Then the R state of the Hemoglobine changes into T state of Hemglobine and
4) the oxigen (O2) decreases because of high altitude
