Eukaryotes have ________ in their cytoplasmic membranes, which serve to strengthen and stabilize the membrane and make it less flexible. Many bacteria have similar molecules, known as ________, in their cytoplasmic membranes that have a similar role.
A) ether bonds / ester bonds
B) lipids / phospholipids
C) sterols / hopanoids
D) phospholipids / lipopolysaccharides

Question

Quizplus · Accepted Answer

Sterols are a type of lipid that strengthen and stabilize the cytoplasmic membrane of eukaryotes. Hopanoids are similar molecules found in the cytoplasmic membranes of many bacteria that have a similar role. Ether bonds and ester bonds are types of chemical bonds and do not relate to the structures found in the cytoplasmic membrane. Phospholipids and lipopolysaccharides are both types of lipids found in bacterial membranes, but they do not serve the same function as sterols or hopanoids in strengthening and stabilizing the membrane.
