Answer 10

H-bond donors and acceptors

Question 11

Vanderwaals Forces occur between

Answer 11

all atoms

Question 12

Hydrophobic effect occurs in

Answer 12

nonpolar groups which causes protein to fold

Question 13

What kind of interactions does a primary protein structure have?

Answer 13

Covalent Bonds: Intramolecular bonds that occur between atoms, amino acids, peptide bonds, and disulfide bonds

Question 14

What kind of interactions does a secondary protein structure have?

Answer 14

Noncovalent bonds: hydrogen bonds that occur between amide groups

Question 15

What kind of interactions does a tertiary protein structure have?

Answer 15

Both covalent and noncovalent: intramolecular bonds, hydrophobic effect, electrostatic interactions, hydrogen bonds, and vanderwaals forces
