The electrical resistance across a living cell membrane is very high because of proteins carbohydrates water lipids in the above 4 which one is correct?
In short, the correct answer is "lipids"
Membrane potential (or transmembrane potential) is the difference in voltage (or electrical potential difference) between the interior and exterior of a cell (Vinterior − Vexterior). All animal cells are surrounded by a plasma membrane composed of a lipid bi-layer with many diverse protein assemblages embedded in it. The fluid on both sides of the membrane contains high concentrations of mobile ions, of which sodium (Na+), potassium (K+), chloride (Cl-), and calcium (Ca2+) are the most important. The membrane potential arises from the interaction of ion channels and ion pumps embedded in the membrane, which maintain different ion concentrations on the intracellular and extracellular sides of the membrane.
What else can I help you with?
What is the function of proteins and carbohydrates that are embedded in a cell membrane?
Proteins embedded in the cell membrane often act as receptors for signaling molecules or transporters for ions and molecules across the membrane. Carbohydrates attached to proteins and lipids in the cell membrane are involved in cell-cell recognition and communication, as well as providing structural support to the membrane.
Does plasma membrane produce proteins?
No, the plasma membrane does not produce proteins. Proteins are synthesized by ribosomes in the cytoplasm and then transported to the plasma membrane to carry out various functions such as transport, signaling, and cell adhesion.
Is the cell membrane a complex combination of carbohydrates and lipids?
Yes, if you add proteins to the list.
What materials are found in the plasma membrane?
The plasma membrane is composed of lipids (phospholipids, cholesterol), proteins, and carbohydrates. These components help maintain the structure and function of the membrane, allowing it to control the passage of substances in and out of the cell.
Which of these materials is not a major component of the plasma membrane?
This membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates. It is mainly phospholipids. The proteins sort of float on the surface of the membrane like islands in the sea.Cholesterol is also found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity.

What types of macromolecules compose the plasma membrane?
Lipids, Proteins and Carbohydrates
Are ion channels carbohydrates?
Ion channels are not carbohydrates but are pore-forming membrane proteins. One of their functions is to include establishing a resting membrane potential.

They help control what enters and leaves the cells.
