What is an example of pentose monosaccharides?
ribose and deoxyribose
How are amino acids joined together?
peptide bonds
What is the structure of a peptide bond?
carboxyl group of one amino acid and the amine group of another amino acid join via dehydration synthesis
C-N bond
What are alpha helix and beta plated sheets held together by?
hydrogen bonds
What was the name of the protein used in Anfinsen’s experiment
ribonuclease
What is ribonuclease bonds?
disulfide bridges
In Anfinsen’s experiment were the proteins able to renature?
Yes
What was the conclusion of Anfinsen’s experiment?
primary structure determines tertiary structure—-why it was able to renature

desmosomes and adhesion junctions are differ how?
in what they are anchored to
iodine transporter experiment?
radioactive iodine is outside of cell, 10 minutes later the radioactive iodine is removed from outside of cell, look to see if there is iodine inside the cell—-needed to a transport protein to move inside the cell
in glucose symporter, does glucose move into our out of cell?
it move glucose into cell against the cell gradient
in glucose symporter, does glucose move into our out of cell?
it move glucose into cell against the cell gradient
What type of protein is a aquaporin?
channel

yes
Desmosomes anchor to the cytoplasm with what type of filament?
intermediate filaments
Adherens anchor to the cytoplasm with what type of filament?
microfilaments
