Proteins that function in the ER will encounter which of the following? enzymatic modification of the ER resident soluble protein to add the KDEL sequence release from KDEL receptor binding in the Golgi due to a pH change anterograde transport in COPII coated vesicles sequestration in the ER by KDEL receptors

anterograde transport in COPII coated vesicles

Explanation:

The endoplasmic reticulum is an organelle involved in protein synthesis, transport, and folding.

COPII is a protein that coats vesicles in the cell, specifically vesicles that transport proteins from the rough ER to the Golgi apparatus, which is the organelle associated with secretion and intracellular transport.

This type of transport is called anterograde transport, as it refers to transport moving moving molecules towards the cell membrane.

that is true   : ) hope this you
