So... what do RBC actually have??

They have no nucleus, no membranous organelles, no mitochondria
I know that they do that Na+/K+ ATPase (But I am assuming ALL cells have these?)
They also obviously have the enzymes needed to preform glycolysis...



I pretty much know what they don't have but I've no idea what they actually carry. Do they have any DNA? Do they have any ribosomes?

Also, because they preform glycolysis with no means to get rid of their NADH (as they have no mitochondria), are they just accumulating huge amounts of lactic acid??

They don't have any organelles. Yes, they have the Na/K pump (all cells do...it's in their membranes, not the organelles). They have the enzymes for glycolysis.

They do have the means of regenerating NAD+. You answered that questions with your last question (ie. the regeneration of NAD+ from NADH by conversion of pyruvate to lactate).

so they don't have a nucleus or ribosomes? where is the hemoglobin stored?

in the cytosol.

RBCs are bags of hemoglobin, essentially.

Technically, they are synthesized with a nucleus. However it is expelled once they mature.
