In a tertiary protein, what happens to hydrophobic and hydrophilic amino acids when placed in water?

• hydrophobic goes inside and hydrophilic stays on outside

• partially folds with hydrophilic on the inside

• nothing will happen whenever it is placed in water

• the protein will become denatured

How would you best describe tertiary protein structure?

• forms 3D structure by R groups interacting w/ each other & environment

• simple sequence of amino acids

• forms alpha helix and beta sheets by forming hydrogen bonds

• multiple polypeptides joined together

How would you best describe secondary protein structure?

• forms 3D structure by R groups interacting w/ each other & environment

• simple sequence of amino acids

• forms alpha helix and beta sheets by forming hydrogen bonds

• multiple polypeptides joined together

What causes surface tension?

• covalent bonds

• hydrogen bonds
