Question

An enzyme functions optimally at 37$^ \circ C$. The enzyme is heated to 60$^ \circ C$ for a short period of time and then the temperature is returned to 37$^ \circ C$. The rate of the enzyme-catalyzed reaction does not return to its previous level. Which best explains whether or not the enzyme denatured?
A. The enzyme denatured because the temperature was raised
B. The enzyme denatured because the rate of the reaction was affected
C. The enzyme does not get denatured because the rate of the reaction was affected
D. The enzyme did not denature because the rate of reaction returned to previous levels
E. The enzyme did not denature because the pH was not changed

Answer 1

Hint: There are various metabolisms taking place in our body. They all occur at a particular speed. To continuously occur these reactions, we need to fasten the process the various chemical reactions have to be catalyzed. These chemicals are present in various sites of the body.

Step by step answer:Enzymes are the proteinaceous biological molecules and chemicals. In the body which catalyzes a reaction taking place in the cells of the body. They serve for a very significant reason. The molecules will take a very long time to react to themselves if the enzymes were not there.
-Option A: The enzyme denatured because the temperature was raised: At the high temperature, the activity of the enzyme decreases variably. This occurs due to the denaturations of the proteins which make the enzymes. This will make the enzyme inactive.
-Option B: The enzyme denatured because the rate of the reaction was affected: At the high temperature as that of 60 $^ \circ C$, the enzyme has already been denatured so the rate of reaction does not bother the denaturation.
-Option C: The enzyme does not get denatured because the rate of the reaction was affected: The enzyme is denatured at a high temperature due to the breakage of peptide bonds. This does not happen due to the rate of reaction but because of the high temperature.
-Option D: The enzyme did not denature because the rate of reaction returned to previous levels: The enzyme has already denatured at the high temperature so the change in the rate of reaction has not occurred yet.
-Option E: The enzyme did not denature because the pH was not changed: The change in the pH affects the enzyme activity so the constant pH will not affect the Enzyme denaturation.
So, the answer is option A: The enzyme denatured because the temperature was raised

Note: There are different types of enzymes in the body. We get enzymes from the diet also. Enzymes never die. They just get denatured and become inactive. Wrong levels of pH and temperature affect their functionality.
