No a red blood cell or erythrocyte is not a protein itself. It does however carry the protein hemoglobin, which is responsible for binding and releasing oxygen atoms, depending on the partial pressure of oxygen.
and a red blood cell or in a red blood cell? if its in a red blood cell i would say haemoglobin
hemoglobin
More than 95 percent of the protein in a red blood cell is hemoglobin. Hemoglobin is a protein that binds to oxygen and transports it throughout the body.
The haemoglobin in the blood i believe.
Sickle cell disease is an inherited blood disorder that affects red blood cells.
Hemoglobin
Hemoglobin
each Red blood cell is capable of transporting oxygen, and carbon dioxide.
Red blood cells are responsible for transporting oxygen throughout the body. They contain hemoglobin, a protein that binds to oxygen in the lungs and releases it to the body's tissues as the blood circulates.
A blood cell carries oxygen by binding it to hemoglobin, a protein found in the red blood cells. Hemoglobin has a high affinity for oxygen, allowing it to efficiently transport oxygen from the lungs to the tissues throughout the body.
A red blood cell is a type of cell without a nucleus. This allows more space for hemoglobin, a protein that helps carry oxygen in the blood.
The main function of a red blood cell is to deliver nutrients--i.e. oxygen, glucose, protein, etc.--to other cells for nourishment that will ultimately maintain homeostasis of the organism.
