Question

Part C - Cell membranes and temperature Hyperthermophiles are organisms that thrive at extremely high temperatures. What sorts of specializations might they have to survive in such high temperatures? Choose all of the correct answers. In the original article (Errington, 2013) referenced in the introductory passage, the authors state that the peptidoglycan cell wall was probably present in the last common ancestor of modern bacteria, if one existed. However, in order to build the cell wall, its components must cross the cell membrane.

Explanation / Answer

Answer: heat stable protein that function at high temperature.

The intrinsic stability factors special proteins called chaperonins are synthesized by hyperthermophiles. Chaperonins function to bind heat denatured proteins and refold them into their active form. The thermosome is a type of chaperonin that is widespread among hyperthermophiles capable of growth above 100
