Which of the Following is NOT a Typical Characteristic of Most

Question

Which of the following is NOT a typical characteristic of most bacterial plasma membranes?
A)site of energy production
B)composed of a phospholipid bilayer
C)contains proteins
D)contains cholesterol
E)is selectively permeable

Accepted Answer

Most bacterial plasma membranes do not contain cholesterol, which is a characteristic of eukaryotic plasma membranes. Bacterial plasma membranes are composed of a phospholipid bilayer, contain proteins, and are selectively permeable, but they are not a site of energy production. Energy production in bacteria typically occurs in the cytoplasm or specialized structures such as mitochondria or chloroplasts in certain bacterial species.
