1.4 Proteins and Enzymes Flashcards
Name 5 different types of Proteins.
Hormones, Enzymes, Antibodies, Receptors, Structural.
What is an Enzyme?
An enzyme is a biological catalyst that speeds up cellular reactions, while remaining unchanged.
What is a degradation reaction?
when something is broken down.
What is a synthesis reaction?
When something is built up.
What is the shape of the active site on an enzyme complimentary to?
it’s specific substrate(s).
what determines the shape and function of a protein?
The sequence of amino acids.
What is formed at the end of an enzyme catalysed reaction?
(End) product(s)
describe the SAM experiment.
Starch is broken down by amylase to make maltose.
amylase
Starch ————————> Maltose
substrate) (enzyme) (product
Describe the HpCOW experiment.
Hydrogen peroxide is broken down by catalase to make oxygen and water.
Catalase Hydrogen ———> Oxygen + Water Peroxide (substrate) (enzyme) (products)
What do we call the temperature or pH at which an enzyme is most active?
The optimum.
What are 2 factors enzymes and other proteins can be affected by?
temperature and pH.
What does the term denatured mean?
The shape of the active site has changed meaning the substrate will no longer fit.
What do we call the molecule that binds with the enzymes active site?
Substrate
