What is the advantage of red blood cells lacking mitochondria?

In most mammals, erythrocytes do not have any organelles (e.g. nucleus, mitochondria ); this frees up room for the hemoglobin molecules and prevents the cell from using the oxygen it is carrying.

What would be an advantage of not having mitochondria?

Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.

How do RBCs survive without mitochondria?

Because RBCs do not contain any mitochondria, they can not utilise oxygen they transport and produce ATP through glycolysis followed by lactic acid fermentation. …

Does RBC have mitochondria?

Mammal red blood cells (erythrocytes) contain neither nucleus nor mitochondria. However, nucleus is too small to hinder erythrocyte deformation. And, there is no sound reason to abandon mitochondria for the living cells.

Why is mitochondria absent in red blood cells Class 9?

Answer Expert Verified The Red Blood Cells (RBC) carry oxygen to the cells. To make this function very efficient, it loses or removes its Mitochondria during a phase called Erythropoiesis. Absence of Mitochondria also gives Red Blood Cells more space to carry oxygen and also to produce ATP, which is an energy carrier.

What would happen if RBC has mitochondria?

If mitochondria are found in RBC, then hemoglobin will have a space deficiency. RBC transfers oxygen from the lungs to other organs. If mitochondria are found in the RBC, then mitochondria will use all the oxygen that had to be transferred to other organs as mitochondria require oxygen for ATP synthesis.

Do RBC have mitochondria?

Mammal red blood cells (erythrocytes) contain neither nucleus nor mitochondria. Traditional theory suggests that the presence of a nucleus would prevent big nucleated erythrocytes to squeeze through these small capillaries. And, there is no sound reason to abandon mitochondria for the living cells.

Why do red blood cells lack a nucleus and mitochondria?

In humans, mature red blood cells are flexible and oval biconcave disks. They lack a cell nucleus and most organelles, to accommodate maximum space for hemoglobin; they can be viewed as sacks of hemoglobin, with a plasma membrane as the sack.

What are the three functions of mitochondria?

Function. The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP), through respiration and to regulate cellular metabolism.
