The function of the specific carbohydrates that are attached to the cell membrane are to provide oxygen membrane. They also provide some fixed energy to various functions of the cell membrane.
No. It is attached to the plasma membrane though, which is important. The cytoskeleton gives cells shape and rigidity etc and so it is important for it to be attached to the plasma membrane. The cytoskeleton is composed of molecules that are located in the cytoplasm but that are attached to the plasma membrane via specific proteins. Hope that helps!
The plasma membrane has one very specific function: Control over what enters or leaves the cell.
Direct activities of the cell give the function of the cell membrane. Globular proteins create narrow passageways or channels. The nucleus directs the cell's functions.
The cell membranes that can act as channels are called integral proteins. Peripheral proteins are the ones that are attached to just one side of the cell membrane.
1. The two lipid layers may differ in specific lipid composition, and each protein has directional orientation in the membrane. The plasma membrane also has carbohydrates, which are restricted to the exterior surface. This asymmetrical distribution of proteins, lipids, and carbohydrates is determined as the membrane is being built by the ER end up on the outside face of the plasma membrane.

NUCLEUS
The plasma membrane has one very specific function: Control over what enters or leaves the cell.
A membrane bound organelle is a membrane bound structure that performs a very specific function within the cell. For example - nucleus, mitochondria, endoplasmic reticulum, golgi apparatus.
Direct activities of the cell give the function of the cell membrane. Globular proteins create narrow passageways or channels. The nucleus directs the cell's functions.
Yes they can be bonded to the outside of cell membranes. The carbohydrates located on the cell membrane are there to help the cell in cell recognition to determine whether a particle close to it is one that it needs to have within it or one that it does not need or that could be potentially harmful to it. They have a specific orientation with the outer layer of the cell membrane to help more fully with the recognition of "self" vs. "other"
A cell membrane is a selectivley permeable membrane. This means that it only lets specific materials get in and out of the cell. The cell membrane helps to let only needed materials into the cell and to get unneeded materials out of the cell. (food goes in waste comes out.)
It act as the covering.It protects the cell.It regulates the entry and exit of materials.It regulates the communication among cells.
