Mature erythrocytes cannot utilize glucose completely because they lack _______________.
Open in App
Solution
The correct option is C Mitochondria
Glucose is metabolized by mitochondria in a number of steps to produce energy or ATP or adenosine triphosphate.
Mammalian erythrocytes or RBSc are non-nucleated cells in their mature form in order to provide more space for hemoglobin. In mammals, erythrocytes also lose all other cellular organelles such as their mitochondria, Golgi apparatus and endoplasmic reticulum.
As mitochondria are absent in RBCs, the glucose cannot be utilized completely.
Thus, the correct answer is option (C), 'Mitochondria'.
