Facts (generated by robot; please edit if you find it inaccurate)

• The mature human erythrocyte is small, round, and biconcave; it appears dumbbell-shaped in profile.
• A secondary consequence of having no nucleus or endoplasmic reticulum is that a mature erythrocyte is unable to carry out protein synthesis.
• The erythrocyte is a unit of protoplasm highly specialized for the functions of O2 and CO2 transport but still containing sufficient repair systems for maintaining itself for about 120 days.
• The plasma membrane (Mg2+)-dependent adenosine triphosphatase from the human erythrocyte is not an ion pump.
• Pre-steady-state uptake of D-glucose by the human erythrocyte is inconsistent with a circulating carrier mechanism.
