Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below. The figure shows the number of cells that have clusters of IRE1 molecules after those cells are treated with various levels of thapsigargin (Tg), a chemical that can induce ER stress. IRE1 can form these clusters when ER stress is induced and this clustering can cause activation of RNAse activity in IRE1. In this experiment, normal IRE1 was used (IRE1α) that can bind to Sec61, along with a modified version of IRE1 that binds to Sec61 more weakly than normal IRE1 (wIRE1α), and another modified version that binds to Sec61 more strongly than normal IRE1 (sIRE1α).

Please help me with this question. More than one answer may be correct. THe graph relating to the information is included below.

The figure shows the number of cells that have clusters of IRE1 molecules after those cells are treated with various levels of thapsigargin (Tg), a chemical that can induce ER stress.

Question 18 options:

IRE1 binding to Sec61 promotes the formation of IRE1 clumps


IRE1 binding to Sec61 prevents the formation of IRE1 clumps


co-translational translocation is a key process


the golgi aparatus is heavily involved in the unfolded protein response


The translocon is involved in the unfolded protein response
