Proteins that are secreted by cells are generally
a. not synthesized on membrane-bound ribosomes
b. initially synthesized with a signal peptide or leader sequence at their C terminal
c. found in vesicles and secretory granules
d. moved across the cell membranes by endocytosis
e. secreted in a form that is larger than the form present in the endoplasmic reticulum
