Ammonia is a very toxic substance especially to the brain cells. Injection of very dilute solutions of it in the blood can comatose a person. This is because
A
Toxic NH4+ ions are formed which penetrate easily through the plasma membrane of brain cells
B
Neutral molecules of ammonia readily combine with glutamate in the blood to yield toxic glutamine molecules
C
Molecules of ammonia readily pass through the mitochondrial membranes cells and consume a-ketoglutrated
D
NH4+ ions affect the brain cell function by changing the polarity of the cell membranes
Answer
NH4+ ions affect the brain cell function by changing the polarity of the cell membranes
