Quizplus · Accepted Answer

Impaired RNA synthesis is not a proposed mechanism of macrocytosis. Macrocytosis, characterized by enlarged red blood cells, is commonly associated with mechanisms such as impaired DNA synthesis (leading to ineffective erythropoiesis and thus larger cells), accelerated erythropoiesis (which can lead to premature release of larger reticulocytes into the bloodstream), and alterations in membrane lipid composition (like increased cholesterol and lecithin, affecting the cell membrane's flexibility and size). However, impaired RNA synthesis is not directly linked to the development of macrocytosis.
