Some signaling molecules secreted by cells into the bloodstream are polypeptides that contain attached polysaccharides. Which of the following cellular structures participate in the production and secretion of such signaling molecules? A) free ribosomes B) ER-bound ribosomes C) Peroxisomes D) Golgi Apparatus E) B and D 8) (2 pts.) Biochemists have been able to study the transport of vesicles along microtubules by purifying vesicles, microtubules and motor proteins and assembling them in a test tube. In order to get successful vesicle transport along microtubules, which of the
