|
What do substrates produce |
products + enzymes
|
|
|
What are all enzymes
|
proteins
|
|
|
in primary structure, what type of bonds link together amino acid chains
|
polypeptide bonds
|
|
|
In secondary structure, alpha helix and beta plated sheets are held together by
|
hydrogen bonds
|
|
|
Tertiary structure is folded and held together by
|
ionic bonds, disulfide bonds, and hydrogen bonds
|
|
|
Quaternary structure also know as globulars, are held together by
|
hydrogen bonds
|
|
|
What is the peak of the graph called were an enzyme can reach full potential
|
optimum
|
|
|
catechol + 1/2 catecholase =
|
benzoquinone
|
|
|
The higher the reaction, what color shows
|
deep red
|
|
|
What is an enzyme
|
catalysts that speed up chemical reactions but are not themselves consumed or changed by the reactions
|
|
|
what is an enzyme
|
catalysts that speed up chemical reactions but are not themselves consumed or changed by the reactions
|
|
|
what is an active site
|
a special area into which substrates (material to be acted on by the enzyme) will fit
|
|
|
What factors may affect the structure of an enzymes active site
|
changes in temperature, alterations in pH, the addition of certian ions or molecules, and the presence of inhibitors
|
|
|
what can affect the rate of an enzyme reactions
|
the relative concentrations of enzyme and substrate in the reaction
|
|
|
What is the enzyme catecholase
|
a enzyme that facilitates a reaction between catechol and oxygen. This shows in peeled potatoes and bruised fruit by the brown color when exposed to the air
|
|
|
In the presence of oxygen, catechol is reduced by what
|
the addition of two hydrogen atoms to form water
|
|
|
above 40 C most enzymes active in living tissue become denatured, which is
|
when a protein's secondary or tertiary structure break down
|
|
|
Define denatured
|
a proteins secondary or tertiary structure breaks down
|
|
|
what can change the way a protein folds
|
the presence of various ions interfere with the pattern of positive and negative charges within a protein molecule
|
|
|
the point at which the enzyme is most active is known as
|
optimum pH
|
|
|
when a substrate fits into the active site of an enzyme a what is formed
|
substrate complex
|
|
|
what does velocity mean
|
the rate of speed
|
|
|
if the amount of enzyme is kept constant but the amount of substrate is gradually increasing, then the velocity at which the enzyme works will increase until what
|
it reaches a maximum
|
|
|
what is the enzyme rennin used for
|
to coagulate the casein of milk during cheese production and serves as a good example of one of the many uses of enzymes
|
