Which of the following gra s- xn )pj7jl3 u4eqj(nphs best illustrates the relationship be g8,ttdib8 5mftween temperature and the activity of enzymes g 5 ,8fmtbtdi8such as lipase?
A.
B.
C.
D.
参考答案: C
本题详细解析:
Choice C is correct because as temperatur s k-vkqaqnp)4f.04 ,ng cqlj7e increases, the activity of enzymes, like lipase, also increases. However, when the temperature surpasses the optimum temperature of the enzyme, the enzyme rapidly denatures and the enzymqnpf-k4l0.7vsn4jqqa),c k ge's activity rapidly decreases.
Choice A is incorrect because above the optimum temperature the enzyme becomes denatured, thus the rate of reaction wouldn't continue to increase.
Choice B is incorrect because the rate of reaction wouldn't plateau, it would start to decrease when the enzyme becomes denatured.
Choice D is incorrect because the rate of reaction wouldn't be highest at the lowest temperature.
