exocytosis

exocytosis的音标为：/"eksəʊsɪtəʊsɪdʒ/，基本翻译为“外排作用”，速记技巧为：细胞膜融合将物质排出细胞。

Exocytosis的英文词源可以追溯到拉丁语ex-和-cytōsis，意为“从内部释放”。其变化形式包括复数exocytosis，过去式exocytosed和现在分词exocytosing。

相关单词包括：

1. Exocytosis（分泌外排）：指细胞内物质从细胞质膜排出细胞的过程。

2. Exocytosis defect（分泌外排缺陷）：一种细胞生物学疾病，表现为细胞内物质无法正常排出。

3. Exocytosis-related protein（与分泌外排相关的蛋白）：一种与细胞内物质排出有关的蛋白质。

这些单词可以进一步描述细胞生物学中的分泌过程和相关疾病，有助于理解细胞内物质的运输和细胞功能的调节。

exocytosis常用短语：

1. exocytosis of neurotransmitters 神经递质的分泌

2. exocytosis of membrane fragments 膜碎片的分泌

3. exocytosis of cytokinesis 细胞分裂物质的分泌

4. exocytosis of digestive enzymes 消化酶的分泌

5. exocytosis of immune cells 免疫细胞的分泌

6. exocytosis of toxins 毒素的分泌

7. exocytosis of hormones 激素的分泌

双语例句：

1. The secretory cells undergo exocytosis, releasing their contents into the surrounding tissue. (分泌细胞通过胞吐作用将内容物释放到周围组织中。)

2. The neurotransmitter is quickly exocytosed from the nerve terminals, allowing for a new round of signal transmission. (神经递质从神经末梢迅速被胞吐出来，从而开始了新一轮的信号传递。)

3. The membrane fragments are exocytosed from the cell, providing the cell with a new source of membrane for membrane repair and growth. (膜碎片被细胞胞吐出来，为细胞提供了膜修复和增长的新来源。)

4. The cytokinesis is completed by exocytosis of cytokinesis factors from the midbody to the daughter cells. (细胞中间部的细胞分裂因子通过胞吐作用被释放到子细胞中，从而完成了细胞分裂。)

5. The digestive enzymes are exocytosed from pancreatic acinar cells, allowing for efficient digestion of food in the gut. (消化酶从胰腺腺泡细胞被胞吐出来，从而有效地在肠道中消化食物。)

6. Immune cells quickly exocytose antibodies upon detection of foreign substances, helping to fight off infections. (免疫细胞在检测到外来物质时，会迅速通过胞吐作用释放出抗体，有助于抵抗感染。)

7. Hormones are released from endocrine cells through exocytosis, regulating various bodily functions. (激素由内分泌细胞通过胞吐作用释放出来，调节各种身体机能。)

英文小作文：

Exocytosis is a crucial process in cells, allowing for the secretion of various substances such as neurotransmitters, hormones, digestive enzymes, and cytokinesis factors. This process plays a vital role in many biological functions, such as communication between nerve cells, regulation of bodily functions, and immune response.

When a cell needs to release its contents, it undergoes exocytosis, which involves fusion of the cell membrane with the secretory vesicle membrane, followed by release of the contents into the surrounding tissue. This process is highly regulated and requires precise coordination between the cell and its environment.

Exocytosis is essential for maintaining health and function of cells and tissues. It allows for the exchange of information between cells, helping to coordinate various bodily processes. Understanding the mechanisms behind exocytosis is crucial for developing new treatments for diseases such as neurodegenerative disorders and immune system disorders.
