Endoplasmic Reticulum

ID #1972

Are the secretory proteins the only proteins that have a signal sequences? And which ribosomes translate the secretory proteins, is it the membrane-bound ribosomes?

Proteins destined to be secreted do present signal sequences as they're being translated, but they are not the only proteins to do so. All proteins that we'll be talking about which present a signal peptide to the cell will be translated on membrane-bound ribosomes.
