“…To maintain the deformability characteristics and its physiological properties, RBCs need energy which is supplied in the form of ATP. In mature RBC, ATP, ADP and AMP form the nucleotide pool of which ATP is the major part (Kim et al 2017). During glycolysis in red blood cells, two molecules of ATP are used up at the hexose level to form phosphorylated compounds.…”

“…Glucose-6-phosphate from glucose and fructose-6-bisphosphate from fructose-6-phosphate whereas, four molecules of ATP are generated at the triose level two molecules each, during conversion of 2 molecules of 1,3-bisphosphoglycerate to 3-phosphoglycerate and conversion of phosphoenolpyruvate to pyruvate. This net gain of two molecules of ATP provide the energy for RBCs (Kim et al 2017).…”

“…Later, this idea has been also supported by the results of Horga et al (7), who showed that incubation of erythrocyte membranes with iso pro terenol, an agonist for the beta-adrenergic receptor, led to the activation of adenylic cyclase. This adrenaline → beta-adrenergic receptor → adenylic cyclase → cAMP pathway was implicated in the increase of oxygen supply, which was induced by high-fat diet-induced hypoxia (8). In that study, activation of beta-adrenergic receptors induced an increase in cAMP, glycolysis, and ATP production.…”

“…Ωστόσο, σε αυτό το μονοπάτι φαίνεται πως η γλυκόλυση οδηγεί κυρίως στην σύνθεση ATP και όχι στην παραγωγή 2,3 διφωσφογλυκερικού. Αποτέλεσμα είναι και πάλι, όμως, η καλύτερη οξυγόνωση των υποξικών ιστών297 .2.1.3 ΠΡΟΣΔΕΣΗ, ΣΥΝΘΕΣΗ ΚΑΙ ΑΠΕΛΕΥΘΕΡΩΣΗ ΜΟΝΟΞΕΙΔΙΟΥ ΤΟΥ ΝΙΤΡΙΚΟΥΤο ερυθρό αιμοσφαίριο συμβάλλει στην οξυγόνωση υποξικών ιστών και μέσω της σύνθεσης και απελευθέρωσης ΝΟ. H αλληλεπίδραση της μη οξυγονωμένης αιμοσφαίνης με νιτρικό, οδηγεί στη σύνθεση NO.…”
