Chapter 4- Enzymes Flashcards
1
Q
What is the definition of an enzyme?
A
A Biological Catalyst
2
Q
What do enzymes help to reduce? Give 2 options.
A
Activation Energy and Rate of Reaction
3
Q
What is formed when the substrate binds to the active site of the enzyme?
A
Enzyme-Substrate Complex
4
Q
How do enzyme break down a substance?
A
R groups on substrate and enzyme interact, which form temporary bonds. These put strain on the bonds within the substrate, which also helps the reaction.
5
Q
What is the main difference between the lock and key hypothesis and the induced fit hypothesis?
A
Shape of the tertiary structure of the enzyme changes to fit around the substrate to interact with R groups to break down the bonds between the molecules.
