IB biology may 2005 Q 7 - rate of reaction

the correct answer is C), how is this interpreted from the graph?
Also why must B) be wrong?

the reason why B) must be wrong is that as the substrate concentration increases, the rate at which product is formed also increases, indicating that the reaction rate increases and not decreases like B) states.

i at least understood the graph that since it is an enzyme controlled reaction, increasing substrate concentration can reach a point to which all enzymes are used and thus the reaction rate would not increase further.

hope this helps! :slight_smile:
