U1 Proteins Flashcards
How is the structure of a protein determined?
Order of amino acids
What are the 5 types of proteins?
Structural, Hormones, Anti-bodies, Receptor, Enzymes
What is an enzyme?
Biological catalysts that are produced by all living cells
What does an enzyme do?
Speed up chemical reactions and remains unchanged in the process
Why does an enzyme only bind with one substrate?
It’s active site is specific
What is an example of a synthesis reaction?
Glucose-1-Phosphate — Phosphorylase —> Starch
What is an example of a degradation reaction?
Starch —Amylase—> Maltose
Where does an enzyme perform best?
At its optimum temperature and pH
What happens when an enzyme is put in extreme temperatures?
It becomes denatured
What happens to the active site when an enzyme denatures?
It changes shape and is no longer complementary to its substrate
What is formed when a substrate binds to an enzyme active site?
An enzyme-substrate complex is formed
