Two important characteristics allow erythrocytes to function as gas carriers.These are:
A) biconcavity and permanent shape.
B) permanent shape and reversible deformability.
C) reversible deformability and biconcavity.
D) biconcavity and the presence of hyperactive mitochondria.

Question

Quizplus · Accepted Answer

Erythrocytes have a biconcave shape which increases their surface area to volume ratio, enhancing their ability to carry oxygen and carbon dioxide. In addition, erythrocytes are able to undergo reversible deformability, meaning they can change shape to squeeze through narrow capillaries and passageways. This allows them to reach all parts of the body, ensuring efficient gas transport. The presence of hyperactive mitochondria, as mentioned in choice D, is not a characteristic of erythrocytes and therefore is incorrect.
