双语版 TED-Ed 演讲精选 This is made possible by an expansive set of digestive enzymes. 这是因为蟑螂有丰富的消化酶。 Osmosis-消化 Trypsin is a pancreatic digestive enzyme that is produced as the zymogen trypsinogen. 胰蛋白酶是一种胰消化酶,以胰蛋白酶原形式产生。 双语版 TED-Ed 演讲精选 It can also secrete saliva with digestive enzymes that liquefy food for easier sucking. 它同时也可以分泌出具有消化酶的唾液来更好的消化食物以帮助吸取。 科学大揭秘 Inside this cavity, certain cells release digestive enzymes, and the food is broken down. 在这个腔内,某些细胞释放消化酶,食物被分解。 Osmosis-消化 Zymogen granules might fuse with lysosomes bringing trypsinogen into contact with lysosomal digestive enzymes. 酶原颗粒可能会和溶酶体融合,使胰蛋白酶原与溶酶体消化酶接触。 Scishow 精选系列 Apple seeds for instance contain a chemical that releases cyanide when it comes into contact with digestive enzymes. 例如苹果籽含有苦杏仁苷(amygdalin,或扁桃苷),一旦遇到动物的消化酵素就会释出氰化物。 Crash Course 解剖生理学篇 And all that saliva delivers enzymes like salivary amylase, a digestive enzyme that breaks down starches into glucose monomers. 所有这些唾液都能传递像唾液淀粉酶这样的酶,这是一种消化酶,可以将淀粉分解成葡萄糖单体。 Osmosis-呼吸 Eventually the pancreas gets damaged, because backed-up digestive enzymes degrade the cells lining the pancreatic ducts, causing local inflammation. 最终胰腺受损,因为储备的消化酶降解了胰腺导管内的细胞,导致局限性炎症。 科学60秒-科学美国人 2023年1月合集 They can apparently withstand all sorts of harsh conditions, like nutrient or oxygen deprivation and attack by digestive enzymes. 它们能显然能抵抗各种艰苦条件,比如养分或氧气缺乏和消化酶的攻击。 经济学人(汇总) These then get snared in their alimentary canals, cannot be broken down by the animals' digestive enzymes and may ultimately kill them. 然后这些东西会陷入消化道,无法被动物的消化酶分解,并最终可能致死。 Osmosis-消化 As the acinar cells become impaired they produce fewer pancreatic digestive enzymes, which results in pancreatic insufficiency. 当腺泡细胞受损时,它们产生的胰消化酶减少,引起胰腺功能不全。 Osmosis-消化 Without digestive enzymes, fat might pass right through the intestines undigested, leading to greasy and smelly stools—called steatorrhea. 没有了消化酶,脂质可能还没被消化就通过了小肠,导致大便油腻发臭——这被称为“脂肪泻”。 Osmosis-解剖与生理 Cholecystokinin stimulates acinar cells in the pancreas to secrete digestive enzymes that travel through the pancreatic ducts and into the duodenum. 胆囊收缩素也能刺激胰腺的腺泡细胞产生消化酶;消化酶从胰腺导管排出,进入十二指肠。 Osmosis-解剖与生理 Bicarbonate helps neutralize the acidic chyme, and raising the pH in the intestinal lumen also helps digestive enzymes work more effectively. 碳酸氢盐能够中和酸性的食糜,还能提高肠腔内的pH值;这也可以提高消化酶的活性。 Osmosis-呼吸 This happens because thick secretions jam up the pancreatic ducts, not allowing digestive enzymes to make it to the small intestine. 因为粘稠的分泌物阻塞在胰腺导管中,使其无法被消化酶分解进入小肠。 Osmosis-消化 Individuals with pancreatic insufficiency might require replacement digestive enzymes and nutritional supplements, and those with diabetes might need insulin-replacement therapy. 胰腺功能不全的患者可能需要消化酶替代治疗及营养补充,而糖尿病患者则需要胰岛素替代治疗。 Scishow 精选系列 So while you're eating cinnaman toast, the bread and the sugar there get broken down by the digestive enzymes in your mouth. 所以的那你们吃肉桂吐司的时候,面包和糖会被口中的消化酶所分解。 Crash Course 解剖生理学篇 Most of those columnar cells secrete mucus, which lubricates everything, and protects your cells from being digested by your own digestive enzymes. 大多数柱状细胞分泌粘液,润滑一切,保护你的细胞不被你自己的消化酶消化。 Osmosis-消化 Acute pancreatitis is inflammation caused by destruction of the pancreas by its own digestive enzymes —a process called autodigestion, and is generally reversible. 急性胰腺炎是胰腺被自身消化酶损伤所致的炎症,称为“自溶”,病情通常是可逆的。 Osmosis-消化 Alright, as a quick recap, your pancreas produces both hormones for the endocrine system and digestive enzymes for the exocrine system. 好!快速回顾下:胰腺产生内分泌系统所需的2种激素胰岛素和胰高血糖素,以及外分泌系统所需的消化酶。

消化酶 Digestive enzyme(重定向自Digestive enzymes)
消化酶(英语:Digestive enzymes)是将聚合的高分子降解为他们的构建单元的酶类,以促进他们被身体吸收。消化酶类可在动物(及人)的消化管内找到,在那里帮助食物的消化,他们也存在于细胞中,特别是在其溶酶体中发挥作用,以维护细胞中的残留物。消化酶类多种多样,他们存在于:由唾腺分泌的唾液之中、由胃内壁细胞分泌的胃液之中、由胰腺外分泌细胞分泌的胰液之中以及在肠(大与小)胃分泌物之中。
英语百科
Digestive enzyme 消化酶(重定向自Digestive enzymes)
Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body. Digestive enzymes are found in the digestive tracts of animals (including humans) and in the traps of carnivorous plants, where they aid in the digestion of food, as well as inside cells, especially in their lysosomes, where they function to maintain cellular survival. Digestive enzymes are diverse and are found in the saliva secreted by the salivary glands, in the stomach secreted by cells lining the stomach, in the pancreatic juice secreted by pancreatic exocrine cells, and in the intestinal (small and large) secretions, or as part of the lining of the gastrointestinal tract. |
