Which is false of the fluid mosaic model of the plasma membrane?
The given statement is false. The fluid mosaic model alludes to the fact that the cell membrane is fluid and the phospholipids are capable of…
Which of the following statement best describes the fluid mosaic model of the plasma membrane?
Which of the following statements best describes the fluid mosaic model of the plasma membrane? right answer feedback: The fluid mosaic model of the plasma membrane is composed of two layers of lipid molecules with protein molecules dispersed within.
Which statement about the plasma membrane is in correct?
Answer (c) It is fluid mosaic and selectively permeable.
What does Mosaic mean in fluid mosaic model?
The fluid mosaic model is a way of describing the structure of cell membranes. The model likens the membrane to a “mosaic” of different components, consisting of a fluid or elastic double layer made up of lipid molecules and large protein molecules.
Why plasma membrane is known as fluid mosaic model?
Explanation: It is sometimes referred to as a fluid mosaic because it has many types of molecules which float along the lipids due to the many types of molecules that make up the cell membrane. … The liquid part is the lipid bilayer which floats along the lipids due to the many types of molecules that make up the cell.
Which statement describes the fluid mosaic model quizlet?
Which statement describes the fluid mosaic model? a phospholipid bilayer with various molecules embedded within and floating between the layers. Facilitated diffusion is a protein‑facilitated movement of solutes across a membrane from an area of higher concentration to an area of lower concentration.
Which sentence best describes the fluid mosaic model?
D is correct. The Fluid Mosaic Model describes the liquid-like movement of the lipids, proteins, and carbohydrates that make up the plasma membrane. These components travel freely across its surface. 3.
Which of these correctly describes the fluid mosaic model and the part of the cell to which it applies?
Which of these correctly describes the fluid mosaic model and the part of the cell to which it applies? Possible Answers: The fluid mosaic model states that lipids and proteins are embedded in the phospholipid bilayer in a mosaic-like pattern; this applies to the cell membrane.
Which of the following functions is performed by the carbohydrates of the plasma membrane?
Functions of Membrane Carbohydrates
Membrane carbohydrates perform two main functions: participate in cell recognition and adhesion, either cell-cell signaling or cell-pathogen interactions, and they have a structural role as a physical barrier.
Which of the following substances does not pass through across the membrane by simple diffusion?
Molecules of oxygen and carbon dioxide have no charge and pass through by simple diffusion. Polar substances, with the exception of water, present problems for the membrane. While some polar molecules connect easily with the outside of a cell, they cannot readily pass through the lipid core of the plasma membrane.
