Term
amino acids
Definition
sub units of proteins
Term
sequence of amino acids
Definition
what determines the shape and function of proteins
Term
protein molecules
Definition
part of the plasma membrane in the phospholipid bilayer
Term
hormones
Definition
made of protein – chemical messengers carried in the blood
Term
antibodies
Definition
made of protein – part of the immune response to infection
Term
enzymes
Definition
made of protein - biological catalysts, speed up reactions & made by all living cells.
Term
active site
Definition
part of an enzyme molecule which is complementary to the shape of a specific substrate (so each enzyme will only work on one substrate).
Term
degradation
Definition
type of reaction where large molecules are broken down into smaller molecules
Term
synthesis
Definition
type of reaction where small molecules are built up into larger molecules
Term
Phosphorylase
Definition
enzyme for: Glucose -1- Phosphate ­-> Starch
Term
Amylase
Definition
enzyme for: Starch -> Maltose
Term
Pepsin
Definition
enzyme for: Protein -> Peptides
Term
Lipase
Definition
enzyme for: Fat -> Fatty Acids and Glycerol
Term
Catalase
Definition
enzyme for: Hydrogen peroxide (H2O2) ->Water (H2O) & Oxygen(O2)
Term
slow
Definition
speed of enzyme controlled reactions at low temperatures.
Term
increases rate
Definition
effect of increasing temperature on rate of enzyme controlled reaction
Term
denatured (changes shape of active site)
Definition
effect of high temperatures (over 40oC) on enzymes
Term
reaction slows then stops
Definition
effect of increasing temperature over 40oC, on enzyme controlled reactions
Term
pH
Definition
factor other than temperature that can affect the rate of enzyme controlled reactions
Term
Optimum
Definition
condition in which the enzyme is most active
