Misfolded proteins in the ER may actively undergo any of the following EXCEPT ... A. being glycosylated and binding to lectins. B. binding to chaperones such as calnexin to prevent aggregation. C. being expelled to the Golgi apparatus for disposal. D. binding to chaperones such as BiP to allow unfolding and refolding. E. being transported back to the cytosol for degradation.

Being expelled to the Golgi apparatus for disposal.

Explanation:

The proper folding of protein is important for the correct biological function of the organisms. The proper folding of protein occurs with the help of chaperones in the endoplasmic reticulum.

The misfolded protein needs to be correctly folded by binding with BiP protein and or be degraded by particular mechanism by sending into the cytosol. because its accumulation in the cell can cause harmful diseases. The misfolded protein can either bind to calnexin and binds to lectin as well. The Golgi is not involved in the disposal of the proteins.

Thus, the correct answer is option (C).

answer:

thousands of years before the arrival of the british, australia was settled by the indigenous people of australia called the aborigines. this timeline begins when the europeans first arrived. 1606 - the first european to land at australia is dutch explorer captain willem janszoon.
