Spectrin
It is biconcave in shape , mature red blood cell do not have nucleus,
sickle cell disease
sickle cell orignates when a red blood cell is too large to fit in the blood vessel and the pressure that is against the it causes it to have a crescent shape
Red blood cell count
It is a donut shape.
sickle-cell disease
The red blood cell's biconcave shape increases its surface area for diffusion. The lack of a nucleus makes this shape possible.
A red blood cell when placed in salty solution shrinks and becomes wrinkled.
A red blood cell has no nucleus and a biconcave shape. This structure allows it to carry oxygen more efficiently.
A red blood cell contains a red pigment known as HAEMOGLOBIN.We know that haemoglobin is a protein.Its structure is quertenary which means its made up of coiled polypeptides.2 beta and 2 alpho.This therefore means the shape of a red blood cell is determined by quertenary structure of its red pigment.
Blood cells are typically disc-shaped with a concave center, resembling a biconcave disc. Red blood cells have this shape to increase their surface area for oxygen and carbon dioxide exchange. White blood cells are larger and varied in shape, allowing them to engulf foreign particles and pathogens.
