The current theory of the structure of the plasma membrane is best described by which of the following models?
A)The fluid-mosaic model
B)The unit membrane model
C)The electrochemical model
D)The nuclear envelope model

Question

Quizplus · Accepted Answer

The fluid-mosaic model is the current and widely accepted theory of the structure and function of the plasma membrane. This model describes the plasma membrane as a fluid structure made up of a lipid bilayer embedded with proteins, glycoproteins, and glycolipids, forming a mosaic pattern. The fluidity of the membrane allows for the free movement of molecules, proteins, and other components within the membrane. This model has been supported by various experimental evidence, such as electron microscopy and biochemical studies. Therefore, choice A is the best answer. Choices B, C, and D are not relevant to the structure of the plasma membrane.
