Which outcome occurs when a fish enters a highly polluted environment containing amphoteric compounds near its isoelectric point?

💡 Explanation

The presence of amphoteric compounds around their isoelectric point reduces the pH gradient necessary for effective gas exchange because it affects membrane transport. Therefore, oxygen exchange decreases rather than increasing uptake, and ammonia excretion isn't enhanced under these specific conditions.
