常见错误

❌ 错误:The enzyme is used for digest.
✓ 正确:The enzyme is used for digestion.

错误:digest 是动词,这里应用名词 digestion。正确用法:enzyme 通常与名词搭配,表示用途。

❌ 错误:Enzymes can be found in many foods, like fruits and vegetables.
✓ 正确:Enzymes are produced by living organisms and can be present in some foods.

错误:酶不是食物本身的成分,而是由生物体产生。正确用法:强调酶的来源和存在方式,避免误导。

近义词辨析

catalyst

catalyst 是更广泛的术语,指任何加速化学反应的物质,包括非生物催化剂;enzyme 特指生物催化剂,通常是蛋白质。

Enzymes are biological catalysts that speed up reactions in cells, while industrial catalysts might be metals or chemicals.

protein

protein 是一大类生物大分子,包括结构蛋白、运输蛋白等;enzyme 是蛋白质的一种,具有催化功能。

All enzymes are proteins, but not all proteins are enzymes—for instance, collagen is a structural protein without catalytic activity.
