Final answer:
Amino acid chains are sent to the ER to be finalized or sent to other parts of the cell. This is true.
Step-by-step explanation:
Amino acid chains are sent to the endoplasmic reticulum (ER) to be finalized or sent to other parts of the cell. This statement is true. The ER plays a crucial role in protein synthesis and modification. Polypeptide chains made on the rough ER are inserted into the ER and then transported to their various cellular destinations. The modified proteins may become part of cellular membranes or be secreted from the cell. The ER also produces phospholipids for cellular membranes.
