An enzyme is a chemical substance a plant or animal makes inside itself. It helps chemical changes happen there — breaking food into smaller bits, building the body’s parts, getting energy out — so those changes do not take forever. Your spit already has an enzyme that starts work on food in your mouth.

an enzyme是enzyme is a chemical substance a plant or animal makes inside itself是植物或動物在自己體內製造的一種化學物質 it helps chemical changes happen there它幫助體內的化學變化發生 breaking food into smaller bits把食物分解成更小的碎塊, building the body's parts建造身體的組成部分, getting energy out還有釋放能量 so those changes do not take forever讓這些變化不用花上一輩子的時間 your spit already has an enzyme你的口水裡就已經有一種enzyme that starts work on food in your mouth會開始在嘴裡對食物起作用

Though actually, you will also meet the word on soap, drinks, and health products in Taiwan. Sometimes the enzymes are doing real work, like lifting stains in cooler water. Sometimes a packet just likes a science glow.

though actually不過其實 you will also meet the word on soap, drinks, and health products in Taiwan你在台灣的肥皂、飲料和保健食品上也會看到這個字 sometimes the enzymes are doing real work有時候裡面的enzyme真的有在起作用 like lifting stains in cooler water像在較冷的水裡去除污漬 sometimes a packet just likes a science glow有時候包裝只是想沾點科學的光

In class, keep the living-helper meaning first. Enzymes are not little animals; they are chemicals the living body makes. Heat and strong acid can stop them working, which is why boiling food changes what they can still do.

in class在課堂上 keep the living-helper meaning first請先記住那個「生物體內小幫手」的意思 enzymes are not little animalsenzymes不是小動物 they are chemicals the living body makes而是生物體製造出來的化學物質 heat and strong acid can stop them working高溫和強酸會讓它們停止作用 which is why boiling food changes what they can still do這就是為什麼把食物煮沸會改變它們還能做什麼
