Mature mammalian red blood cells (erythrocytes) undergo a specialized development process during which they lose both their nucleus and their mitochondria.
Which of the following processes is a mature erythrocyte still capable of performing?
Regenerating ATP via oxidative phosphorylation on the inner mitochondrial membrane
Maintaining intracellular ion concentrations via ATP-dependent active transport
Transcribing genes to replace worn-out membrane channel proteins
Translating existing mRNA templates into functional enzymes on the rough endoplasmic reticulum
