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.

Cell membranes are asymmetrical which is a most likely explanation?
Cell membrane proteins are determined as the membrane is being packaged in the ER and Golgi. or The two sides of a cell membrane face different environments and carry out different functions.
Where do we find ions gradients in cell membranes?
Gradiend occurs between two places. Mainly either sides of membrane
What are cell membranes and cell wall composed of?
The cell membrane and the cell wall is are composed of two different things. The cell membrane is made from phospholipid bilayers that becomes flexible by cholesterols. The cell wall is a rigid structure that surrounds the cell membrane that is either composed of cellulose, chitin, or peptidoglycan depending on the cell.
What kinds of proteins can be found in cell membranes?
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
What cell has two membranes?
scientists aren't really sure, and haven't found any cells with two membranes. yes, a plant cell has two membranes, each different: cell membrane and cell wall
What is membrane sidedness?
The cell membrane regulates the flow of materials in and out of the cell. Membrane sidedness is an important concept in cell biology because to gives a better understanding on how the cell membrane functions.

What are two structures that are common is prokaryotic and eukaryotic cells?
Cell membrane, made of different stuff, but both have a cell membrane. Flagella, much smaller and different, but both can have flagella.
What is a cell membrane of?
There are multiple membranes in a cell. Two of them are the cell membrane and the nucleur membrane.
Why does a cell with a cell wall need a membrane?
A cell that has a cell wall still needs a cell membrane because the two structures have different functions. A cell wall gives the cell shape, support and protection whereas a cell membrane controls what enters and leaves the cell. Also, the cell theory states that all cells have a cell membrane.

What are some function that the cel membrane do?
he cell membrane forms a barrier between the inside of the cell and the outside, so that the chemical environments on the two sides can be different. The cell controls those differences so as to optimize the workings of the chemical machinery inside the cytoplasm. The cell also causes brief changes in the internal environment by moving stuff across the membrane in a controlled way. These changes are the ways in which cell respond to events in the outside world

The cell wall is a rigid structure that surrounds the cell membrane that is either composed of cellulose, chitin, or peptidoglycan depending on the cell.
What are two names of the cell membrane?
The cell membrane (also called the plasma membrane or plasmalemma) is the biological membrane separating the interior of a cell from the outside environment.
