lipids
No, a cell membrane is mainly composed of phospholipids, cholesterol, and proteins. Triglycerides are a type of lipid that serve as an energy storage molecule within cells, but they are not a major component of cell membranes.
The molecule will be transported across the membrane by way of a transport protein or protein channel.
dna
No, phospholipids are the main component of the cell membrane, not fat. Phospholipids have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails, which help form the structure of the cell membrane. Fat (or lipids) can also be found in the cell membrane, but they are not the main component.
The cell wall or membrane keeps it separate from the environment.
The cell membrane
No, a cell membrane is mainly composed of phospholipids, cholesterol, and proteins. Triglycerides are a type of lipid that serve as an energy storage molecule within cells, but they are not a major component of cell membranes.
Phospholipids are the major component of cell membranes, but there are proteins, glycoproteins and cholesterol also in the membrane.
The molecule that will not pass through the phospholipid bilayer of a membrane is a large and polar molecule.
Cholesterol is the small molecule that decreases the fluidity of the plasma membrane.
A component is the Sodium ion channel.
The cell membrane contains phospholipids.
permeability
permeabiity
The molecule will be transported across the membrane by way of a transport protein or protein channel.
dna
No. Lipids are an essential and major component of the cell membrane
