Question

rate of reaction
which part of the graph
displays the denaturing of an
a
c
d
b

Explanation:

Denaturing of enzymes (or proteins) causes a decrease in reaction rate as their active sites lose structure. In the graph, part C shows a decrease in the rate of reaction, which corresponds to denaturing (e.g., due to factors like temperature/pH beyond optimal, causing enzyme structure loss and reduced activity). Part A is an increase (e.g., enzyme working better initially), B is the peak (optimal rate), D is a stable low rate. So C is where denaturing - related rate decrease occurs.

Answer:

B. C
