Question

Which of the following helps in maximum transport of oxygen?
a. Red blood corpuscles
b. Platelets
c. Plasma
d. White blood corpuscles

Answer 1

Answer:

Hemoglobin

Explanation:

Hemoglobin (Heme + Globin) The protein hemoglobin is a molecule which is responsible for carrying almost all of the oxygen in the blood. It is composed of four subunits, each with a heme group plus a globin chain. The heme group is composed of a porphyrin ring which contains an iron (Fe) atom in its center.

Answer 2

a. Red blood corpuscles and (c) Plasma helps in maximum transport of oxygen.

Explanation:

• Three percentage of oxygen is carried in dissolved state through the plasma.
• Maximum carbon dioxide transport in the form of bicarbonate.
• Some of the carbon dioxide is transported dissolved in the plasma. Some carbon dioxide is transported as carbaminohemoglobin.
• However most carbon dioxide is transported as bicarbonate.
• As blood flows through the tissues carbon dioxide diffuses into red blood cells where it is converted into bicarbonate.
• The relatively small amount in plasma attributable to a lack of carbonicanhydrase plasma so an association with water is slow plasma plays little role in buffering and combination with plasma proteins is poor.
• The protein hemoglobin is a molecule which is responsible for carrying almost all of the oxygen in the blood.
• It is composed of four sub units each with a heme group plus a globin chain.
• The heme group is composed of a porphyrin ring which contains an iron atom in its center.
