O The hemoglobin concentration is decreased O The Hb02 concentration is increased. O The oxygen concentration is increased D The oxygen concentration is decreased Submit Hb(a) +02(9) Hb02(aq) an athlete first arrives at high altitude My Answers Give Up Part B In what direction does the hemoglobin equilibrium shift?

Explanation / Answer

the oxygen concentration is decreased

at High Altitudes Dynamic Equilibrium When a system is changing at the molecular level, but its macroscopic properties remain constant Why do athletes train in high altitude? gamow bag Hb+4O2 Hb(O2)4 body tissue O2 more hemoglobin=more O2 In High Altitude Hemoglobin In Relation to Equilibrium -Oxygen concentration at high altitudes is lower than at sea level

-This is a "stress" and the Hb equilibrium reaction responds by counteracting this lower than usual oxygen level.
