Solution
The red blood cells (RBCs) lack mitochondria. Hence, TCA cycle does not take place in the RBCs. RBCs metabolize glucose mainly via glycolysis followed by lactic acid cycle. The lactate is released from the cells at the end of complete consumption of 1 molecule of glucose.
Hence, total 2 ATP molecules are produced by consumption of one molecule of glucose in RBC.
