proteins which contain all 20 amino acids
ex dairy and meat

what are complete proteins?
example?

9

proteins that lack one or more essential protein or are very low
ex. vegetables fruit

What are incomplete proteins?
example?

10

catalysts which speed reactions

what are enzymers?

27

they are specific and match up with only one substrate

how to enzymes fit with a compound

28

high tempertures, changes in pH

what destroys enzymes?

29

they become denatured, their shape changes and they no longer function properly

what happens when enzymes interact with high temperatures and changes in pH

30

the substrate
ex maltose-maltase

what are they usually names after?

what does your immune system attack

42

make substances inactive

what is a competitive inhibitor?

43

binds with enzyme where it wont matter but changed the enzyme so substrate cant fit
