Stomach acid breaks the enzyme down and reduces its activity.

胃酸会分解这种并降低其。

To protect the pancreas, the acinar cells manufacture inactive forms of the enzymes called proenzymes, or zymogens.

为了保护胰腺，腺泡细胞会产生这些无形式，称为“原”。

Then near these CRISPR locations are Cluster associated or Cas proteins, many of which have enzymatic activity.

这些CRISPR位点附近有基因编码成簇相关蛋白，即Cas蛋白，它们许多都有。

This work has led to the creation of proteins with new enzymatic activities, able to catalyze useful chemical reactions.

“这项研究创造出具有新型蛋白质，这种蛋白质可以催化有益化学反应。

He therefore wondered if he could isolate the enzyme's active centre and yet preserve its activity. In fact, he did better.

因此，想知道是否能分离出这种中心，同时又能保持它。事实上，做得比想象中更好。

Their main method of destruction is blocking the action of enzymes called RNA polymerases.

它们主要破坏手段是抑制被称为RNA聚合。

Researchers used directed evolution to improve the enzyme's activity.

研究人员使用定向进化来提高。

It takes a lot of enzymatic activity, a lot of blood flow.

它需要和血液流动。

So without nitric oxide, you have less telomere, telomerase enzyme, and that telomerase enzyme isn't functional.

因此，若缺乏氮氧化物， 端粒会减少，端粒也会降低， 导致该端粒功能失常。

We can find an enzyme that has some starting activity, some clay that we can work with.

我们可以找到一种具有初步，一些可以利用土壤。

So now once we have the enzyme inside the active site, there's going to be a chemical tug.

因此，一旦进入位点，就会发生化学拉力。

As the antibody- antigen complex circulates in the blood, the complex " fixes" complement to it.

结果是，补体激了强产生，穿透了细菌细胞壁，并使细菌有机体破裂。

Dr Hazen has shown, in yet further experiments on mice, that microbe-generated TMAO interferes with liver enzymes that make bile acids—substances that help remove excess cholesterol.

Hazen博士已经由在老鼠中进行后续实验证实，细菌产生TMAO干扰肝脏，后者可产生胆酸，一种有助于清除过多胆固醇物质。

But heavy drinking can alter enzyme activity so more of that byproduct is produced, potentially causing liver damage even with what's usually a safe dose of acetominophen.

但是饮酒却会使发生变化。即便只是服用乙酰氨基酚安全用，因饮酒而被分解出更多副产物得以残留，进而可能会导致肝损伤。

Efforts are underway to seek methods to inhibit the enzyme activity of DPP4, which holds the potential to enhance the efficacy of existing medications and even discover new treatment approaches.

目前正在努力寻找抑制 DPP4 方法，DPP4 有可能提高现有药物疗效，甚至发现新治疗方法。

They saw significantly increased levels of cleaved caspase activity, specifically within the cancer cells, but only when IFNU was present and presumably activating this whole pathway.

们观察到，裂解型半胱天冬水平显着升高，且主要出现在癌细胞内，但仅在IFNγ存在并可能激该整个通路情况下才出现。

And the problem is they both use the same enzymes to convert into their active forms, and so a high omega-6 load can crowd out omega-3 conversion.

问题在于它们都需要相同才能转化为形式，因此高omega-6会抑制omega-3转化。

In addition to estrogen, the granulosa cells also secrete a hormone called activin, which stimulates FSH production, as well as binding to FSH receptors, and the activity of granulosa cell aromatase as well.

除了雌激素，颗粒细胞还会分泌一种激素叫做激素，它可以刺激FSH分泌，与FSH受体结合；并且与颗粒细胞芳香有关。

And maybe more importantly, when the hydrochloric acid is combined with pepsinogen, an inactive enzyme that's secreted by another kind of stomach cell called chief cells, the mixture creates the protein-digesting enzyme pepsin.

也许更重要是，当盐酸与胃蛋白原结合时，胃蛋白原是一种非，由另一种被称为主细胞胃细胞分泌，混合物产生蛋白质消化胃蛋白。

Because digestion is such an active process and particularly digesting animal protein that's high in fat, high in protein, requires a lot of blood flow, a lot of enzymatic activity that leads to a lot of dilation and flushing.

消化是一个高度跃过程，尤其是消化高脂肪、高蛋白动物蛋白质，需要血液流动和，这导致了广泛血管扩张和面部潮红。
