Enzymes Details Flashcards
Process of enzyme action
-Substrate enters active site of enzyme
-Enzyme changes shape slightly as substrate binds
-Enzyme changes substrate into products
The shape of the active site is…
complementary to only one specific substrate
Factors which impact enzyme activity
-Temperature
-pH
Impacts of temperature on enzyme activity
-Causes denaturation(if temperature is too high above the optimum temperature)
-Kinetic energy of molecules increases(unless temperature is too high)
-Changes shape of enzyme(heat can break its bonds, which disrupts its shape and the shape of its active site, rendering it useless)
-Frequency of effective collisions increases(unless temperature is too high)
Impacts of pH on enzyme activity
-Causes denaturation
-Changes shape of enzyme(disrupts bonds within the enzyme causing it to lose its shape)
