Which of the following statements about biological membranes is FALSE? Which of the following statements about biological membranes is FALSE? Lipids and proteins move laterally at approximately the same rate within the membrane. Phospholipids often require a specialized enzyme to facilitate movement across (flipping) the membrane. The faces of biological membranes are distinct and usually different in both composition and structure. They are composed of a mixture of lipids and proteins in which lateral diffusion of components is possible.

Larissa Hodge · Answer 1

Option (1).

Explanation:

Biological membrane mainly composed of lipids and proteins with the small amount of carbohydrate exposed on the outer surface of the membrane. This membrane plays an important role as it separates the cellular environment and facilitate the transport of the selected molecule.

The flippase enzyme is required to transport the molecules from one side of the membrane to the other membrane. Lipids and proteins can undergo lateral motion but at the different rate within the membrane.

Thus, the correct answer is option (1).
