Chapter 3 - proteins structure and function Flashcards
What are proteins?
the molecular. machines that do a cells work
What is ATP? Where does it live? and What type of source is it?
its an enzyme that produces ATP, it lives in the mitochondria and chloroplast of a cell and its an energy source
Whats an polymer?
Its monomer thats attached to itself multiple times
what is the monomer for proteins?
amino acids
CO are what time of bonds? & why?
they are polar bonds
OH are what type of bonds? & why?
polar bonds
where are the hydrophobic amino acids when a protein structure is folded? why are they in the locate they are in?
they are inside the protein structure when folded, they are inside because hydrophobic amino acids do NOT like being in water
why do hydrophobic amino acids do not like being in water?
opposites attract, the fact the amino acid is hydrophobic it means the amino acid does NOT like being in water
what is the reaction of many monomers combining together?
polymerization
what kind of bonds hold primary structures together? & why that specific bond?
covalent bonds, because covalent bonds are the strongest and for the primary structure since it is a base of the protein it needs the strongest bonds holding them together
what kind of bond hold second, tertiary ad quadrature structures?& why that specific bond/
hydrogen bonds, because as the going up within the protein structure more layer structures are getting added so, weaker bonds are holding them together. They are also easily taking apart.
what type of bonds hold amino acids? & why?
covalent bonds hold amino acids together, because they are the strongest bonds. Amino acids make up the primary structure, which is the base of proteins. They need a strong base to form a protein
what type of bonds fold protein and why?
hydrogen/weak bonds because the folds of a protein can always unfold and be taken apart
what are chaperones?
chaperones are a group of protein inside of a cell that bind to hydrophobic amino acids of an unfolded protein to help the protein to fold.
what are polypeptides?
two or more amino acids linked together
