Phospholipids moving freely and allowing water and other hydrophobic molecules to pass through int or out of the cell is known as what?

Phospholipids moving freely and allowing water and other hydrophobic molecules to pass through into or out of the cell is known as fluid mosaic model. This model describes the structure of the cell membrane as a fluid lipid bilayer with embedded proteins that can move laterally to allow for the passage of molecules.


The plasma membranes of all known cells are largely composed of what class of macromolecules?

The plasma membranes of cells are largely composed of lipids, specifically phospholipids. These phospholipids form a bilayer structure that provides a barrier for the cell, regulating the passage of molecules in and out of the cell.


What component of the membrane causes it to have a fluid consistency?

Phospholipids can move within the bilayer but most of the lipids and proteins drift laterally. Flip flopping doesn't happen very often. When temperatures are cool, the fluid state goes to a solid one. Though it stays fluid at lower temperatures if it has lots of phospholipids with unsaturated hydrocarbon tails.


Why cell membrane also known as fluid mosaic?

That is the name of the current model of cell membranes. It was named like that because of the structure of the membrane; billions of tiny phospholipids group together in what is called a bilayer, and resemble a mosaic. These phospholipids move and "drift", thus allowing certain substances through as gaps in the membrane open and close. This movement is where the fluid part of the name came from.


What part of the plasma membrane is hydrophilic?

The plasma membrane is a dynamic structure. It is composed of 2 layers of lipid material with protein molecules interspersed through out. The phospholipids move at a rate of 2um. /sec. while the proteins move at a much slower rate. The phospholipids have 2 definite ends, a hydrophilic (focusing to the outside and inside of the membrane) and a hydrophobic one (forming the center of the membrane

Can phospholipids move laterally along the plane of the membrane?

Yes, phospholipids can move laterally along the plane of the membrane. This movement is known as lateral diffusion and it allows for flexibility in the structure of the cell membrane. Lateral diffusion is influenced by factors such as temperature and composition of the membrane.


Fill in the blank phospholipids and proteins move or side to side for short distances?

I believe lateral movement is your answer, but im on the same question in my cell bio class, so this is just what I have found so far. I know they can move also in restricted spaces or not all.


It is also known as phosphoglycerides?

glycerophospholipids- glycerol based phospholipids


Why does the flexibility of a membrane increase when more phospholipids are present?

The flexibility of a membrane increases when more phospholipids are present because the phospholipids can move around and adjust their positions more easily, allowing the membrane to bend and stretch without breaking.

Is vacuoles composed of phospholipids and other embedded molecules?

Yes, a vacuole is made up of phospholipids and other embedded molecules. The vacuole is also known as a cell membrane.


The basic unit of the cell membrane is the?

Phospholipids.


Can phospholipid move?

Yes, phospholipids can move within cell membranes. They are able to move laterally, which helps maintain the fluidity and flexibility of the membrane. Additionally, some phospholipids can also flip-flop between the two layers of the membrane, although this process is less common.


Where are phospholipids found in eucaryotic cells?

The cell membrane, also known as the "phospholipid bilayer".


Chemicals that move in and out of cells by diffusion?

The cell cotains phospholipids ,proteins , and carbohydrates. Carbohydrates can be attached to either the phospholipids or the proteins in the cell membrane. Sometimes carbohydrates (sugars) are attached to cell membrane phospholipids and to cell membrane proteins


Is a phospate molecule a fat?

1. The ion phosphate is anorganic and not a fat. 2. Many phospholipids are known.


Phospholipids can move freely and allow water and other hydrophobic molecules to pass through into or out of the cell. This is known as simple sugars because it does not requires?

Phospholipids form the cell membrane, which is selectively permeable, allowing water and hydrophobic molecules to pass through. This movement is facilitated by simple diffusion due to the fluidity of the phospholipid bilayer, without requiring energy input from the cell.
