It has a pore that passes potassium ions and calcium ions.

它有个开孔，能让钾离子和钙离子通过。

Glutamate binds to NMDA receptors which tell the cell to open up calcium ions channels.

谷氨酸与NMDA受体结合，使细胞钙离子通道打开。

Usually though, bile salts bind up the calcium ions and keep them from binding with and precipitating unconjugated bilirubin.

通常情况下，胆盐会结合钙离子，以此阻止钙离子与非结合胆红素结合并沉淀。

Its walls are loaded with calcium pumps — which use ATP to save up a bunch of calcium ions.

它的壁上装有钙泵——它使用三磷酸腺苷来储存一堆钙离子。

Our research aims to reveal the atomic structures of membrane proteins that take sugars, calcium ions, and sodium ions into our cells.

我们的研究旨在揭示将糖、钙离子和钠离子带入我们细胞的膜蛋白的原子结构。

Normally, the resting state of sodium channels is stabilized by calcium ions, which prevents them from spontaneously opening and potentially causing depolarization.

正常情况下，钙离子用来稳定钠离子通道的静息状态，这可以防止钠离子通道自发打开，从而导致去极化。

This flow of positively-charged calcium ions causes all those tiny synaptic vesicles to fuse with the cell membrane and purge their chemical messengers.

这种带正电荷的钙离子流动导致所有这些微小的突触囊泡与细胞膜融合并清除它们的化学信使。

Heat-sensitive proteins on those nerve endings will respond by changing their shape, allowing sodium and calcium ions to flood into the skin's nerve cells.

这些神经末梢上的热敏蛋白会通过改变它们的形状做出反应，让钠离子和钙离子涌入皮肤的神经细胞。

Immediately after a muscle fiber is stimulated by a nerve — when calcium ions are flooding into the sarcomeres to pull away those two protein bodyguards of tropomyosin and troponin from the actin — that's called the latent period.

肌肉纤维被神经刺激后立即——钙离子涌入肌节，将肌动蛋白中保护原肌球蛋白和肌钙蛋白的蛋白质带走——这称为潜伏期。

It also has calcium ions dissolved in it—for the purpose of the exercise is to encourage the bacteria to generate from the ingredients provided crystals of calcium carbonate a few microns across—a process called biomineralisation.

它还含有溶解在其中的钙离子——因为该练习的目的是鼓励细菌从所提供的成分中产生几微米宽的碳酸钙晶体——这一过程称为生物矿化。

It is the consequence of a mutation in a calcium ion channel gene Ion specific channels of which calcium channels are a subclass belong to a different group of transmembrane proteins from the channel redopsins.

它是钙离子通道基因突变的结果。离子特异性通道是钙通道的一个子类，属于与通道红细胞蛋白不同的跨膜蛋白组。
