WebWhat is metabolism of RBC? RBC metabolism includes the glycolytic pathways producing both energy (as adenosine 5- triphosphate, or ATP) and oxidation-reduction intermediates that support oxygen transport and membrane flexibility. … The storage lesion is a blanket term used to encompass all of the bad things that happen to RBCs during storage. WebThe red blood cell (RBC) is a marvel of cellular evolutionary specialization. Whilst often considered simplistic owing to its absence of nuclei and other cellular organelles, this inability to respond transcriptionally and to replenish components through new protein synthesis necessitates complex post-translational mechanisms through which the cell is …
