question 10 of 25
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 changes faster than b.
b. enzyme a reacts with less substrate than b.
c. enzyme a becomes a better catalyst than b.

Explanation:

Examine the slopes of the rate - temperature curves for both enzymes. For Enzyme A, the rate of enzyme action increases and then decreases more sharply as temperature changes compared to Enzyme B. The steeper decline in the rate of Enzyme A indicates it changes faster with temperature. There is no information about substrate quantity in the graph and no indication that one enzyme is a better catalyst overall.

Answer:

A. Enzyme A changes faster than B.
