What makes a polypeptide?

• the ribosome

• the smooth er

• rough er

The correct 3D shape/ structure of a polypeptide is called the ______

• native

• conformation

• orientation

• reagent

What a protein is supposed to look like. Can be altered by changing conditions such as the pH or temperature or treating with certain chemical agents.

• Native conformation

• conformation

• orientation

• common structure

When does protein folding begin?

• after the protein is complete

• at secondary structure

• at tertiary structure

• as the polypeptide chain emerges from ribosome

This molecule assists in the assembly of some proteins and help proteins fold.

This protein deals with incorrect Disulfide bonds by breaking the bond and allowing the bond to reform

• Ire1

• Disulfide Isomerase

• Ubiquitin

• Proteasome

Select all that are part of the 3 stages of cell protein regulation
