Which of the following statements about the GroEL subunit is FALSE? Group of answer choices The inside of the GroEL subunit facing the central chamber is nonpolar. Seven GroEL subunits are packed side-by-side, forming a ring that surrounds a central water-filled cavity. The GroEL equatorial domain binds ATP. The GroEL subunit undergoes an allosteric conformational change.

What type of chaperone is GroEL-GroES? Choose one: A. chamber type B. disulfide isomerase C. heat shock protein D. clamp type Part 3 (0.3 point) If a semi-conservative mutation occurred in the GroEL gene that abolished ATP binding, what functional consequence would you predict? Choose one: A. The mutated GroEL subunit would be denatured. B. The GroEL complex would form but would not act as a chaperone. C. The seven GroEL subunits would not come together to form the barrel-like structure, but would persist as folded monomers. D. Activity of the GroEL-GroES chaperone would be greatly elevated, more quickly refolding proteins.

Which of the following statement about the chaperonin GroEL/S is correct? GroEL/S binds partially folded protein by hydrophilic residues. GroEL/S can fold two proteins at the same time because it is composed of two ring structures. GroEL/S can fold proteins of any sizes. One cycle of protein folding in GroEL/S system requires hydrolysis of seven ATP molecules.

15. Disulfide bonds are more likely to be formed ___ of the cell, due to the ___ environment there. a. Inside; oxidizing b. Inside; hydrophobic c. Outside; reducing d. Outside; oxidizing e. Inside; reducing 16. Which statement does NOT describe a feature of the E. Coli GroEL/GroES chaperonin system? a. The conformational changes in GroEL/GroES do not require external energy input. b. An unfolded protein binds to the hydrophobic surface of the GroEL chamber. c. Constraining a protein inside the GroEL chamber restricts the conformational space a protein can explore while folding. d. Constraining a protein inside the GroEL chamber prevents protein aggregation. e. All of these function in the process of the GroEL/GroES chaperonin.
