In the blood, most (60%) of the carbon dioxide moves through plasma as which of the following substances?
A) Bicarbonate
B) Lactic acid
C) Carbonic acid
D) Formic acid
E) Acetate
Bicarbonate
A buffer component that regulates acid-base balance in the body, especially important in the bloodstream and digestive system.
Carbon Dioxide
An invisible, scentless gas generated from the combustion of carbon and organic substances, as well as through the process of breathing. It exists naturally in the atmosphere and is taken in by plants during the process of photosynthesis.
Lactic Acid
A chemical byproduct of anaerobic respiration, mostly known for causing muscle fatigue and soreness during intense physical activity.

Final Answer :
A
Explanation :
Most of the carbon dioxide in the blood is transported as bicarbonate ions (HCO3-) in the plasma. This occurs through a process where CO2 combines with water to form carbonic acid (H2CO3), which quickly dissociates into bicarbonate and hydrogen ions.
