有一種說法認為: endocytosis是內吞,一般是受體介導的(receptor-mediated),具有“目的”性。 pinocytosis是胞飲,簡單的說就是cell drinking,把細胞周圍的體液(含特殊溶質在內)一起喝掉,這個過程的nonspecific and non-absorptive。 但也有說法認為,endocytosis 包含pinocytosis and phagocytosis,后兩者之間存在細微的差別,前者是cell drinking, 后者是cell eating。參見wiki。。 不管是哪一種,你就記得pinocytosis是無差別喝掉就行了。 |

Word Origin for endo- from Greek, from endon within. Word Origin and History for endo- word-forming element meaning "inside, within, internal," comb. form of Greek endon "in, within," literally "in the house of". cytosis: 1. Suffix referring to cells, as in anisocytosis (inequality in the size of red blood cells), elliptocytosis (elliptical red cells), and phagocytosis (ingestion of cells). 2. Suffix connoting an increase in cells, as in leukocytosis (increase in white blood cells) and lymphocytosis (increase in lymphocytes). ----------------------- The prefix (phago- or phag-) means to eat, consume, or destroy. It is derived from the Greek phagein, which means to consume. Related suffixes include: (-phagia), (-phage), and (-phagy). Phagocytosis (phago-cyt-osis) - the process of engulfing and destroying microbes, such as bacteria, or foreign particles by phagocytes. ----------------------- pino-, pin- (Greek: a combining form confused between three Greek roots and may mean "hunger", "dirt", or "drink"; and there is one Latin form referring to the "pine tree" .pinocyte, pinocytic, pinocytosis, pinocytotic [Greek, "drink"]: The inbibition [drinking]; of liquids by cells; i.e., absorption of liquids by cells, especially the mechanism by which cells ingest extracellular fluid and its contents. |

:d 胞飲作用 胞飲作用(英語:pinocytosis)是細胞內吞作用(endocytosis)從外界獲取物質及液體的一種類型,是細胞外的微粒通過細胞膜的內陷包裹形成小囊泡(胞飲囊泡),并最終和溶酶體相結合并將囊泡內部的物質水解或者分解的過程 原文: [胞飲作用 ]( https://zh.wikipedia.org/wiki/%e ... e%e4%bd%9c%e7%94%a8 ) |
