This changing chemistry could scramble that message, or it could damage the lobsters' smell receptors.

这种不断变化的化学物质可能会扰乱该信息，或者可能会损害龙虾的气味感受器。

But one or two solid sharp sniffs will ensure that more air gets to your smell receptors.

但是一两次强烈的嗅觉将确保更多的空气进入你的嗅觉感受器。

And these smell receptors firing alone or in combination is what gives your brain the perception of a particular smell.

这些气味感受器单独或组合激发，让你的大脑感知到特定的气味。

In fact, a lot of what we perceive as flavour comes from odour molecules that float up to our smell receptors through our mouths.

事实上，我们所感知到的很多味道都来自气味分子，这些气味分子通过我们的嘴浮到我们的嗅觉感受器上。

According to Professor Russell Keast, variations in our smell receptor (or olfactory receptor) genes determine what we taste when we eat Coriander.

根据 Russell Keast 教授的说法，我们的气味受体（或嗅觉受体）基因的变异决定了我们吃香菜时的味道。

Well, the female's urine carries a critical chemical signal that works because it can pass through seawater and lobsters have a smell receptor that can detect and receive the message.

好吧，雌性的尿液携带着一种重要的化学信号， 这种信号之所以起作用， 是因为它可以通过海水， 而龙虾有一种可以检测和接收信息的气味感受器。
