The primary function of the respiratory system is to exchange oxygen and carbon dioxide Inhaled oxygen enters the lungs and reaches the alveoli Oxygen passes quickly through this air blood barrier into the blood in the capillaries Similarly carbon dioxide passes from the blood into the alveoli and is then exhaled

blood rich in oxygen enters the lungs through the pulmonary artery in where the alveoli within the lungs exchange carbon dioxide and oxygen so the carbon dioxide leaves your body.

lana [24]

Answer:

The correct answer is -transfer fixed carbon dioxide to cells in which the Calvin cycle occurs

Explanation:

In C4 plants the light reaction and Calvin cycle occurs in two different cell that are mesophyll cell and bundle sheath cells. First, the CO₂ is fixed into 4- carbon oxaloacetate by an enzyme PEP carboxylase.

Then this oxaloacetate is converted into a simpler form called malate. Malate molecule then enters into bundle sheet cell and there it releases one molecule of CO₂. This CO₂ enters the Calvin cycle which results in the sugar formation with the help of enzyme rubisco.

Therefore by releasing of CO₂ molecule by malate in bundle sheet cells, it transfer fixed carbon for the Calvin cycle to occur.
