Enzymes Details

Question 1

Process of enzyme action

Answer 1

-Substrate enters active site of enzyme
-Enzyme changes shape slightly as substrate binds
-Enzyme changes substrate into products

Question 2

The shape of the active site is…

Answer 2

complementary to only one specific substrate

Question 3

Factors which impact enzyme activity

Answer 3

-Temperature
-pH

Question 4

Impacts of temperature on enzyme activity

Answer 4

-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)

Question 5

Impacts of pH on enzyme activity

Answer 5

-Causes denaturation
-Changes shape of enzyme(disrupts bonds within the enzyme causing it to lose its shape)
