[单选题]
Which of the followingya4-+4m bfrai statements describes grzk04.j+oh d7/hrkgic8 e:l how enzymes interact with substrates d rr0:c/zge4lgh k+. oijk 8h7to catalyze reactions?
I. Enzymes and substrates in solutions collide with one another, and the substrate is bound at the active site.
II. There is more movement of the substrate in a reaction because the substrate is usually smaller than the enzyme in size.
III.When the substrate binds to the active site, the shape of the enzyme changes slightly so it can accommodate the substrate.
A. I, II and III
B. I and II only
C. I and III only
D. II only
参考答案: C
本题详细解析:
Statements I and III are correct and describe how enzymes interact with their 3zk237p6*n*eam 3pzab rypjfb3fd9 b specific substrates. Statement II is incorrect because, in many catabolic reactions, the substrate is la p6zn3p erf7b 3b9kbjm 3f pa3d*y2*azrger than the enzyme.
