A protein that is bound for secretion from a cell is produced by ; ( C ) Ribosomes found on the rough endoplasmic reticulum
Proteins bound for secretion are produced by the Ribosomes that are found on the rough endoplasmic reticulum because the Ribosomes synthesizes the protein chain while sending it to the cisternae ( contained in RER ).
The proteins synthesized and sent to cisternae are then secreted from the surface of RER.
Hence we can conclude that A protein that is bound for secretion from a cell is produced by Ribosomes found on the rough endoplasmic reticulum.
