What is the role of mitochondria in RBCs?

Answers

Answered by Itzgoldenking

Answer:

Ferrochelatase (FECH) is an enzyme found in mitochondria that adds iron ions (Fe2+) into protoporphyrin to produce heme (Figure 1). This biochemical reaction is critical for cell health. ... The best-known protein that contains heme is hemoglobin, which is the oxygen-carrying protein in red blood cells

$<body bgcolor=fushchia><maruee direction="right"><font color=yellow>$ All mitochondria have the same functions in all cells where they appear, their most important role is to import pyruvate, ADP and phosphate and from this synthesize and export ATP (see cellular respiration).

However: In the process of nucleated RBCs becoming mature erythrocytes, all their organelles are jettisoned — to accommodate more hemoglobin — in a process called enucleation. From Wikipedia article Red Blood Cell (bold added):

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