The internal portion of a plasma membrane

has proteins within it that will tend to have their hydrophobic amino acids on their outer surfaces.

Which of the following interactions involve attraction between partially charged atoms?

hydrogen bonds

Proteins that are to be secreted from a cell

B and C

At normal human physiological pH (approximately 7.4), a free amino acid (not bound to other amina acids) is typically found in the zwitterionic form. This means the amino acid has

A and C

Which of the following is/are true about water?

A and B

Which of the following is/are true regarding hydrophobic interactions?

The tertiary structure of proteins found within the cytoplasm of a cell is such that their hydrophobic amino acids tend to be found on the internal regions of the folded protein.

Benzoic acid (CHsCOOH) can dissociate to benzoate (CHsCOO) and a proton. Also, the pka of benzoic acid is 4.19. From this information it can be concluded that

a benzoic acid solution at pH = 4.19 will be composed of equal concentrations of C6HsCOOH and CoH,COO

In an RNA molecule, each phosphate is bound via an ester linkage to

A and B

In two-dimensional gel electrophoresis of proteins, different proteins in a sample are separated based on differences in their

A and B

Dr. Moe Baio is studying the receptor protein mGluR5. He wants to isolate this protein from several different mouse tissues (e.g. brain, lung, heart, liver, etc.) Of the following, which technique would be best for him to use to isolate this protein?
