Final answer:
Chaperones are ER resident proteins that aid in folding of new proteins and bind carbohydrate chains.
One example of a chaperone protein is BiP, which is located in the endoplasmic reticulum (ER) and assists in the folding of newly synthesized proteins.
Step-by-step explanation:
ER resident proteins that aid in folding of new (nascent) proteins and bind carbohydrate chains are called chaperones.
Chaperones play a crucial role in protein folding and help ensure that proteins acquire their correct three-dimensional shape.
One example of a chaperone protein is BiP (Binding immunoglobulin Protein), which is located in the endoplasmic reticulum (ER) and assists in the folding of newly synthesized proteins.
