Effect of Temperature on Enzyme Activity

Flashcards defining key vocabulary related to the effect of temperature on enzyme activity, reaction rates, and enzyme denaturation.

Optimum temperature

The temperature at which enzymes show maximum activity.

Enzyme-substrate (E-S) complexes

Complexes formed when substrates collide with enzymes, leading to the formation of more products.

Active site

The region of an enzyme that can be changed or destroyed by excessive heat energy, preventing substrate molecules from fitting into it.

Denatured

The condition of an enzyme when its three-dimensional ($3\text{-D}$) structure is lost and its active site is destroyed due to heat above optimum temperature.

Rate of reaction

Increases as temperature rises due to faster movement of molecules and a greater number of collisions between substrates.
