WebDrawn by J. Shaw at BYU-Idaho, Winter 2014. In the tissues, carbon dioxide levels elevate, so it diffuses into blood and enters the red blood cells to be converted to carbonic acid by the enzyme carbonic anhydrase. Hydrogen ions are released and bind to hemoglobin causing more oxygen to be released to the tissues (Bohr effect). WebHemoglobin is a globular protein made up of four subunits, each with a heme group. One oxygen molecule is carried by each heme group. The heme groups are linked to one another by a weak ionic connection. The four subunits are linked together by salt bridges and hydrogen bonds in a tetrahedral configuration. The Function of pH
