What gas is a waste product carried by the blood?
A
oxygen
B
water
C
nutrients
D
carbon dioxide
Explanation: 

Detailed explanation-1: -In the human body, carbon dioxide is formed intracellularly as a byproduct of metabolism. CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.

Detailed explanation-2: -Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled.

Detailed explanation-3: -Answer and Explanation: Cellular respiration and alcohol fermentation generate carbon dioxide as a waste product. There are two types of cellular respiration, aerobic and anaerobic. Carbon dioxide is only released in aerobic respiration.

Detailed explanation-4: -It is a waste product that your body makes when it uses food for energy. Your blood carries carbon dioxide to your lungs. When you exhale, you breathe out carbon dioxide. Having too much or too little carbon dioxide in your blood can be a sign of a health problem.

Detailed explanation-5: -Carbonic acid almost immediately dissociates into a bicarbonate anion (HCO3-) and a proton. Thus, bicarbonate is the primary means by which carbon dioxide is transport occurs throughout the bloodstream according to the equation CO2 + H2O–> H2CO3–> H+ + HCO3-.
