Extreme thermophiles have ________ chains in their membrane in order to maintain membrane stability.
A) lipoprotein
B) hopanoid
C) cholesterol
D) terpenoid
E) cardiolipin

Question

Quizplus · Accepted Answer

Extreme thermophiles have terpenoid chains in their membrane in order to maintain membrane stability at high temperatures. Terpenoids are hydrocarbon chains with multiple isoprene units, which give them a high degree of saturation and rigidity, making them ideal for use in high-temperature environments. Lipoprotein, cholesterol, hopanoid, and cardiolipin are found in other types of membranes, but not specifically adapted for extreme thermophiles.
