Approximately seventy percent of carbon dioxide absorbed by the blood – InterviewSolution

InterviewSolution

1.	Approximately seventy percent of carbon dioxide absorbed by the blood will be transported to the lungsA. as bicarbonate ionsB. in the form of dissolved gas moleculesC. by binding to RBCD. as carbaminohaemoglobin
Answer» Correct Answer - A The largest fraction of carbon dioxide, i.e, about 70% is converted to bicarbonates ` (HCO_(3)^(-))` and transported in the plasma , in the presence of enzyme carbonic anhydrase. `CO_(2)+H_(2)O overset("Carbonic")underset(" anlydrase")hArrunderset(("Carbonic acid"))(H_(2)CO_(3))underset("anlydrase")overset("Carbonic")hArr underset(("Bicarbonate ion"))(HCO_(3)^(-)+H^(+))`
