WebWhat is the primary feedback used by the brain to control breathing? a. heart rate b. partial pressure of O2 c. blood pH, which indicates O2 level d. blood pH, which indicates CO2 level Web(2) Bohr shift describes how the oxygen dissociation curves relates to carbon dioxide [remember GCSE: respiration]. As carbon dioxide and/or acidity increases, the binding affinity of haemoglobin for O 2 decreases. [Higher level: Carbon dioxide forms carbonic acid due to action of carbonic anhydrase in RBC.

WebPartial pressure reflects the relative amount of gas in a mixture and is measured in millimeters of mercury (mm Hg). Llamas are native to the Andes Mountains in South America. The partial pressure of O2 (abbreviated PO2) in the atmosphere where llamas live is about half of the PO2 at sea level. As a result, the PO2 in the lungs of llamas is about … onshore paddling youtubeWebSep 7, 2024 · The Bohr shift helps the body release more O2 to respiring tissues when the blood pH is more acidic. During exercise, a lot of CO2 is produced, which results in larger amounts of hydrogen ions that acidify the blood. Thus, the Bohr shift lets the body know it's exercising.
