Recent research has identified several adaptive mechanisms through which red blood cells regulate oxygen delivery, including NO-driven changes in membrane deformability, Cys93-dependent S-nitrosylation, adenosine-mediated stimulation of glycolysis and 2,3-BPG production, and the formation of hypoxic memory via degradation of eENT1 ( Beyond their role in gas exchange, erythrocytes participate in a wide range of metabolic and signaling processes
More than 62 proteins are involved directly in transcription, nucleotide metabolism, (de)phosphorylation, or (de)ubiquitinylation, which are all essential processes for cell cycle progression [50]
This includes activities outside of the gym like heavy housework and outdoor landscaping, and lawn work too
