Question

Approximately 70% of carbon-dioxide absorbed by the blood will be transported to the lungs
A) as bicarbonate ions
B) in the form of dissolved gas molecules
C) by binding to RBC
D) as carbaminohemoglobin

Answer 1

Basically every particle of carbon dioxide delivered by digestion must exist in the free structure as it enters blood in the tissues and leaves vessels in the lung. Between these two occasions, most carbon dioxide is moved as bicarbonate or carbamate.

Complete answer:
Carbon dioxide- It is frequently alluded to by its equation $CO_2$.It is available in the Earth's air at a low focus and goes about as an ozone harming substance. In its strong state, it is called dry ice. It is a significant part of the carbon cycle. Barometrical carbon dioxide gets from different normal sources including volcanic outgassing, the ignition of natural issue, and the breath cycles of living oxygen consuming life forms; man-made wellsprings of carbon dioxide come mostly from the consuming of different petroleum derivatives for power age and transport use.

Transport of Carbon Dioxide in the Blood: _Carbon dioxide atoms are moved in the blood from body tissues to the lungs by one of three strategies: disintegration legitimately into the blood, authoritative to hemoglobin, or conveyed as a bicarbonate particle. A few properties of carbon dioxide in the blood influence its vehicle. To start with, carbon dioxide is more dissolvable in blood than oxygen. Around 5 to 7 percent of all carbon dioxide is broken up in the plasma. Second, carbon dioxide can tie to plasma proteins or can enter red platelets and tie to hemoglobin. This structure transports around 10% of the carbon dioxide. At the point when carbon dioxide ties to hemoglobin, an atom called carbaminohemoglobin is shaped. Officials of carbon dioxide to hemoglobin are reversible. In this manner, when it arrives at the lungs, the carbon dioxide can openly separate from the hemoglobin and be removed from the body.

Thus, the option (A) is the correct answer.

Note: In people, carbon dioxide goes as gas disintegrated in the fluid aspect of the blood by interfacing with hemoglobin protein particles as bicarbonate particles. More than 2/third or about 70% of carbon dioxide ventures along these lines.
