Question

what happens to the enzymes in a persons body when their body temperature returns to normal after a fever? a they regain their shape and normal activity b they stop working c they turn into different kinds of enzymes d they create new enzymes

Explanation:

Enzymes are proteins. A fever (elevated body temperature) can temporarily disrupt the weak bonds (like hydrogen bonds) that maintain an enzyme's shape. But when the body temperature returns to normal, these weak bonds can re - form. As a result, the enzyme can regain its original shape (tertiary structure) and its normal activity. Option b is incorrect because enzymes do not stop working permanently after a fever. Option c is wrong as enzymes do not chemically transform into different kinds of enzymes due to a fever. Option d is also incorrect because the existing enzymes do not create new enzymes in this context.

Answer:

A. They regain their shape and normal activity
