Choose the right sequential phenomena among the following during the delivery of \[{{O}_{2}}\]from blood to tissue.

P: Absorption of \[C{{O}_{2}}\] by the blood.

Q: Reaction of absorbed\[C{{O}_{2}}\], with \[{{H}_{2}}O\] to form \[{{H}_{2}}C{{O}_{3}}\] within RBC and its conversion into \[{{H}^{+}}\] and \[HCO_{3}^{-}\] ions in the presence of carbonic anhydrase enzyme.

R: Reaction of absorbed\[C{{O}_{2}}\], with \[{{H}_{2}}O\] in plasma to form \[HC{{O}_{3}}\] and its conversion into \[{{H}^{+}}\]and \[HCO_{3}^{-}\] ions in the presence of carbonic anhyrase enzyme.

S: Combination of \[{{H}^{+}}\] with home portion of\[Hb{{O}_{2}}\], to release\[{{O}_{2}}\].

T: Combination of \[HCO_{3}^{-}\]with heme portion\[Hb{{O}_{2}}\], to form reduced hemoglobin and release of\[{{O}_{2}}\].
