Which outcome arises when a protein molecule misfolds within a cell's endoplasmic reticulum?

💡 Explanation

When a protein misfolds, exposed hydrophobic regions trigger the unfolded protein response (UPR) because chaperones cannot properly assist folding. Therefore, the UPR activates to restore homeostasis, rather than increasing ATP, lipid synthesis, or cell division, which would not directly address protein misfolding.
