Question

The graph below shows how two different enzymes react with a substrate as the temperature increases.

Based on the results, what conclusion can be drawn about the action of the enzymes as the temperature increases?

A.Enzyme A uses up all the substrate faster than B.
B.Enzyme A changes faster than B.
C.Enzyme A reacts with less substrate than B.
D.Enzyme A becomes a better catalyst than B.

Answer 1

Both enzymes exhibit reduced activity at higher temperatures, likely due to denaturation of the enzyme proteins.

Step-by-step explanation:

In the graph showing how two different enzymes react with a substrate as the temperature increases, it can be observed that both enzymes initially increase their reaction rate as the temperature increases. However, as the temperature continues to rise, the reaction rate for both enzymes decreases. This decrease in reaction rate indicates that the enzymes become less effective at higher temperatures, potentially due to denaturation of the enzyme proteins.

Therefore, based on the results, the conclusion that can be drawn about the action of the enzymes as the temperature increases is that both enzymes exhibit reduced activity at higher temperatures, which is likely due to denaturation of the enzyme proteins.

Answer 2

Enzyme: A changes faster than B
