Question

GPT-4o mini · Answer

The correct response is: **The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.** Enzymes, which act as catalysts in biological reactions, have an optimal temperature range where their activity is maximized. As the temperature rises, the kinetic energy of molecules increases, leading to more frequent and effective collisions between enzymes and substrates, resulting in an increased reaction rate. However, if the temperature continues to rise beyond a certain point, the enzyme may become denatured, losing its functional shape and, therefore, its activity, ultimately leading to a decrease in the reaction rate.
