Protein Function Flashcards
What are the two types of proteins?
- Globular
- Fibrous
What are fibrous proteins used for?
To create very long structures which provide structural integrity.
They have structure and are stretched out with repeating patterns.
What are globular proteins and what are they used for?
They are individual units, usually one or a few peptides, rolled up into one structural ball and perform chemical tasks.
What are the different classes of globular proteins?
- Antibodies
- Membrane channels
- Enzymes
What are the different classes of fibrous proteins?
- Collagen
- Silk
What do antibodies do?
They recognise foreign species and elicit an immune response.
What do enzymes do?
Catalysis
They transform chemical reactions through catalysis.
What do membrane proteins do?
Chemicals
They transport chemicals and information across biological barriers.
They do this by sitting within a membrane and forming a channel to transport information.
What do enzymes do?
Pathway
They change the energy pathway to get to the products by decreasing activation energy.
How do enzymes increase rates of reaction?
Environment
They make the environment just right for the reaction so the reactants can be brought together at the best position.
What are the different enzymatic reactions?
- Oxidoreductases
- Transferases
- Hydrolases
- Lyases
- Isomerases
- Ligases
- Kinases
