土壤的底层决定了植物生长。
reactant在化学反应中泛指参与反应的物质,但在酶促反应中与substrate同义,需注意语境。
substance是极泛指的术语,仅在生化语境中可替代substrate,日常使用不精确。
material强调作为原料或基础,但substrate专指酶作用的特定分子,不可随意互换。
compound指化学上纯净的化合物,substrate多为化合物,但并非所有化合物都是酶底物。
grammar · medium
易错句子The enzyme substrates the compound.
正确表达The enzyme acts on the compound as a substrate.
错误将名词 substrate 用作动词,正确使用动词短语 act on 或 use as a substrate。
grammar · medium
易错句子The cells grow in the substrate.
正确表达The cells grow on the substrate.
介词误用:substrate 是支撑物或表面,通常搭配介词 on,而非 in。
substrate 在科学中指酶作用物或生长基底;substance 泛指任何物质,不强调功能或位置。
substrate 在生物学和化学中用,substratum 偏地质或哲学指底层。
