Module 2 Lecture 3 Flashcards
1
Q
Threshold Energy
A
Also known as Activation energy
2
Q
Exergonic reaction
A
- Products have less energy than reactants
- Activation energy prevents reaction
3
Q
How can the activation energy be affected?
A
Catalyst
4
Q
A
5
Q
Catalysts
A
- increases the rate of a chemical reaction
- lowers the activation energy
- unchanged after a reaction
- Enzymes are a type of catalyst
6
Q
Enzymes
A
Decrease Activation Energy
Most biological reactions would proceed too slowly to detect without enzymes
7
Q
Enzyme Structure
A
- Proteins
Polymers of amino acids
Joined by peptide bonds
7

A
Active site
8
