When blood leaves the capillary bed most of the carbon dioxide is in the form of
(A) carbonate ions
(B) bicarbonate ions
(C) hydrogen ions
(D) hydroxyl ions
Answers
Explanation:
option b is the correct answer
Answer:
Carbon dioxide enters the bloodstream directly, is attached to plasma proteins or haemoglobin, or is transformed to bicarbonate. The correct answer is B.
Explanation:
Carbon dioxide travels via the circulation to the lungs, where it is eventually expelled from the body by expiration. Carbon dioxide has several functions in the human body, including blood pH control, respiratory drive, and haemoglobin oxygen affinity.
Carbonic anhydrases (CA) are enzymes that catalyze the fast conversion of carbon dioxide to bicarbonate and are important in Carbon dioxide transport for cell respiration.
The majority of the carbon dioxide that diffuses into the capillaries and eventually into red blood cells interacts with water in a chemical process mediated by the enzyme carbonic anhydrase, resulting in carbonic acid. Carbonic acid dissociates nearly instantly into a bicarbonate anion and a proton. Bicarbonate is a kind of carbon dioxide, a byproduct of combustion.
