A. Activates the enzyme involved in the reaction.
B. Facilitates binding of the substrate to the active site.
C. Speeds up the rate of reaction.
D. Reduces the rate of reaction.
参考答案: D
本题详细解析:
Inhibitors prevent enzymes from cac4 z0/dkjvp 11v(g1ddlrco3 xm) yg4etalysing reactions and therefore decrease the rate of enzyme catalysed reactions.
Inhibitors do not activate enzymes, thereby increasing the rate of reaction (Choice A).
Inhibitors do not help the substrat/ vdy 1gczo1vd p(0 rkec443)1gdmljx e bind to the active site (Choice B). In fact they usually prevent the substrate from binding to the active site.
Inhibitors decrease the rate of reaction, they do not speed it up (Choice C).
