Question

multiple choice question
bacterial membranes are lipid bilayers within which proteins float. what is the relative proportion of these two components?
90% lipid + 10% protein
70% lipid + 30% protein
50% lipid + 50% protein
20% lipid + 80% protein

Explanation:

Bacterial cell membranes typically have an approximate 50:50 ratio of lipids to proteins, as proteins play critical roles in transport, signaling, and structural support alongside the lipid bilayer framework.

Answer:

C. 50% lipid + 50% protein
