Effects of ROS on cell metabolism are well documented in a variety of species. These include not only roles in apoptosis (programmed cell death) but also positive effects such as the induction of host defence genes and mobilization of ion transporters. This implicates them in control of cellular function. In particular, platelets involved in wound repair and blood homeostasis release ROS t… WebHemoglobin The amount of Hb F present is a function of the number of reticulocytes that contain Hb F, the extent of selective survival of Hb F–containing reticulocytes that become mature Hb F–containing erythrocytes (F cells), and the amount of Hb F per F cell.
