Mature red blood cells do not contain all of the usual organelles. red blood cells lack a nucleus and do not contain mitochondria, endoplasmic reticulum, or centrioles. based on this information, which of the following is true?

mature red blood cells produce all the atp for cellular functions because they carry the oxygen on hemoglobin.
mature red blood cells produce large amounts of protein (hemoglobin) during their short life span.
mature red blood cells do not divide and therefore have a short life span.
mature red blood cells divide quickly and produce the atp using aerobic respiration

The correct answer is statement 3rd.

Explanation:

The RBCs are the most general kind of blood cell and the primary means of transporting oxygen to the body tissues through blood flow via the circulatory system.  In humans, the developed red blood cells are devoid of the nucleus, and the majority of the cell organelles, in order to make most of the space for hemoglobin, can be witnessed as the sacks of hemoglobin.  

Due to this characteristic of RBCs of not possessing a nucleus and other major organelles at the stage of maturation the cells are not allowed to differentiate and thus exhibit a short life span.
