Rainbow trout use acetylcholinesterase to break down the neurotransmitter acetylcholine.Researchers measured the rate at which this happened at 17°C and after the fish was acclimatized to 2°C.Their results showed that the rate was close to the same at both temperatures.Which is the most likely explanation for this result?

Question

Quizplus · Accepted Answer

The most likely explanation for the enzyme maintaining its activity rate at both temperatures is that the fish can produce two different forms of the enzyme, each optimized for a different temperature range. This allows the fish to efficiently break down acetylcholine across a wide temperature range, ensuring proper neurological function.
