Question

6. Use the information and the graph below to answer the following question.All changes SoredScientists wanted to student the effect of water temperature on the swimming speed of goldfish. They set up and experiment in which they raised populations of goldfish in two different environments.Population 1 was raised at 5°C. Population 2 was raised at 25°C. All other variables were constant in both aquariums. The results of this experiment are shown in the graph below.SWIMMING SPEEDS OF TWOGOLDFISH POPULATIONSods Sun MS aderas10 20 30 40 50Water Temperature 'OKEY- Population 1 raised at S'O--- Population 2 (raised at 25Which of these is most affected in the cells of the goldfish when the water temperature is lowered?O salt concentrationO enzyme activityO pH levelODNA base sequence

Answer 1

The rate of an enzyme-catalyzed reaction increases as the temperature increases. However, at high temperatures, the rate decreases again because the enzyme becomes denatured and can no longer function. Now, at lower temperatures, the enzyme rate decreases. In fact, all enzymes have a range of temperatures when they are active, but there are certain temperatures at which they work optimally.

So that, we can conclude that the correct answer is:

Enzyme activity
