(24 cards)
what happens to the enzyme after the reaction?
nothing
explain what is meant by the term specific?
only works on one substrate
explain the difference between synthesis and degradation enzymes?
synthesis- making something (build up)
degradation- breaking down
sub-units of a protein?
amino acids
share meaning
structural, hormones, antibodies, receptors, enzymes
4 functions of a protein
enzymes, hormones, antibodies, structural
list 4 properties of an enzyme?
unchanged, reused, only reacts, active site
substrate, enzyme and product
fat, lipase, fatty acids
optimum meaning?
best conditions for enzyme
denatured meaning?
active site changes shape
describe the effect of temperature on enzyme activity
low temperature- enzyme is reduced
what are all proteins made of?
amino acids
what is a protein?
a type of cell
what conditions does each enzyme work best at?
optimum
what is a percentage change?
change in value divided by the starting value x 100
what does structural mean?
found in the cell membrane
what does hormones mean?
chemical messengers that travel in the blood
what does antibodies mean?
fight infection, defend again pathogens
what does receptors mean?
transmit information from outside to inside the cell
what does enzymes mean?
speed up chemical reactions
what is an enzyme?
a biological catalyst that speeds up chemical reactions
what does synthesis mean?
sticks together
which factors affect an enzyme?
temperature/ph
what is the active site?
the place on an enzyme where the SUBSTRATE binds/attaches
