Answer: The biconcave shape of erthrocytes is as a result of PERIPHERAL PROTEINS anchored to the inner surface of their plasma membrane.

Explanation:

Erthrocytes or red blood cells are cells produced by the bone marrow which transport oxygenated blood through out the body. The biconcave shape of red blood cells is as a result of peripheral proteins anchored to the inner surface of their membrane plasma.

The biconcave shape increases the flexibility of erthrocytes which allow the red blood cells to travel through capillaries with tiny size of diameter, give the red blood cells large surface area and increase their abilities to transport oxygen.

Answer:

peripheral proteins anchored to the inner surface of their plasma membranes

Explanation:

The anchored of peripheral proteins to the inner surface of RBC plasma membrane which makes them thick or plump  at the peripheral and thin at the center, is an adaptive feature of RBC for increasing the surface area to volume ratio of RBC for transport of maximum molecules of oxygen by binding with haemoglobin( which occupies the centre,)

The  biconcave nature also ensure passage of RBC by squeezing through tight and narrow capillaries  to reach needed tissues.
