Which physiological outcome results when toxic ammonia accumulates inside teleost gills?

💡 Explanation

When ammonia accumulates, diffusion gradients across the lamellae are reduced because the concentration gradients that normally drive ammonia excretion and oxygen uptake are compromised, disrupting oxygen uptake efficiency. Therefore lower oxygen causes harm, rather than enhanced excretion or improved chloride transport, which require different membrane transport mechanisms.
