Question

from the image given above, what does the rising portion of the curve describe?
select the correct answer below:
the substrate concentration is increasing with increasing temperature.
the substrate concentration is decreasing with increasing temperature.
the rate of the reaction catalyzed by the enzyme is increasing with increasing temperature.
the rate of the reaction catalyzed by the enzyme is decreasing with increasing temperature.

Explanation:

Step1: Analyze the x - axis and y - axis

The x - axis is temperature and the y - axis is activity.

Step2: Understand the relationship

As temperature increases (x - axis), the activity (y - axis) is rising. In the context of enzyme - catalyzed reactions, activity is related to the rate of the reaction. Substrate concentration is not indicated on either axis. So, the rising portion of the curve means the rate of the reaction catalyzed by the enzyme is increasing with increasing temperature.

Answer:

The rate of the reaction catalyzed by the enzyme is increasing with increasing temperature.
