question 29
predict how a fever of 40°c (104°f) would affect enzyme activity.
a the enzymes would be unaffected by the temperature increase, as long as ph remains the same.
b the activity of the enzymes would slow down dramatically.
c the enzymes would catalyze more reactions due to the higher temperature.
question 30

Explanation:

Enzymes are proteins, and high temperatures (such as 40°C which is above normal human body temperature of around 37°C) can denature proteins. Denaturation changes the shape of the enzyme's active site. When the active - site shape is altered, the substrate cannot bind effectively (as per the lock - and - key model of enzyme - substrate interaction).

Answer:

B. The activity of the enzymes would slow down dramatically.
