Question

According to the uid-mosaic model of the plasma membrane Select one: a. Phospholipids form a double layer, with the hydrophilic heads facing each other in the center. B. The membrane is a rigid structure. c. Proteins are free to move within a double layer of phospholipids. d. Protein and phospholipids form a regular, repeating structure.

Answer 1

c. Proteins are free to move within a double layer of phospholipids.

Step-by-step explanation:

According to the fluid mosaic model, proteins and phospholipids can move laterally and rotate in their place. This is one of the characteristics of the fluid mosaic model. The fluidity of the membrane's components depends on factors such as temperature, the presence of cholesterol, and if the fatty acid chains of the phospholipids are saturated or not.
