Question

Question 10: The human body maintains a temperature of around 98.6 degrees at all times. Enzymes are involved in almost every chemical reaction in the body. Which of the following describes the connection between these two statements? (SC.912.L.18.1 and 18.11)  

Enzymes function best at a specific temperature.  

The body needs to be warm to prevent hypothermia.

The body is kept relatively warm to prevent too much enzyme action.

There is no connection between the two statement.

Answer 1

Enzymes function best at a specific temperature.

Explanation: Most human enzymes have an optimal temperature near normal body temperature (~37°C/98.6°F). Keeping body temperature stable ensures enzymes work efficiently; too low temperature slows enzyme activity, and too high temperature can denature enzymes and stop reactions. The other choices are incorrect because the goal isn't merely to prevent hypothermia or to “prevent too much enzyme action.”
