Question

multiple choice question
which type of lipids compose a bacterial plasma membrane?

○ cholesterol
○ integral protein
○ phospholipid
○ hopanoid

Explanation:

• Cholesterol is not present in bacterial plasma membranes (it is found in eukaryotic membranes).
• Integral protein is a protein, not a lipid, so it is not the correct category.
• Hopanoids are lipid-like molecules that can be present in some bacterial membranes but are not the primary structural lipid component.
• Phospholipids form the fundamental bilayer structure of bacterial plasma membranes, making them the main lipid component.

Answer:

C. Phospholipid
