Do all cell membranes contain the same kind of proteins in the same relative locations?
No. Though all cell membranes have the same general characteristics outlined in any Biology textbook, they are all unique in type of proteins. Cell membranes between members of the same species will differ, and membranes within the same individual with differ also. The location of proteins will differ too, since they are subject to drifting and relocation. Some integral proteins will move slowly or not at all due to their connection to the cytoplasm, but others take advantage of the fluidity of the phospholipid bilayer.
What else can I help you with?
Most cell membranes are composed principally of?
Most cell membranes are composed principally of phospholipids, which have a hydrophobic tail and a hydrophilic head. These phospholipids form a lipid bilayer that acts as a barrier to control what enters and exits the cell. Additionally, cell membranes also contain proteins, cholesterol, and carbohydrates.
Cell membranes are composed primarily of what type of molecule?
Cell membranes are composed primarily of phospholipids. These phospholipids form a lipid bilayer that acts as a barrier to the passage of most molecules. Additionally, cell membranes also contain proteins, cholesterol, and carbohydrates.
What is the internal membranes found in chloroplast called?
The internal membranes found in chloroplasts are called thylakoid membranes. Thylakoid membranes house the pigments and proteins necessary for the light-dependent reactions of photosynthesis. These membranes are arranged in stacks called grana.
Cell membranes are made of all macromolecules except?
Of the major biomolecules, lipids, carbohydrates, proteins and nucleic acids, only nucleic acids are not present in cell membranes. Lipids make up the bilayer; proteins craete pumps and channels; carbohydrates are part of glycoproteins but no RNA or DNA is present.
What role do chromosomes play when a cell make proteins?
They contain the information to make the proteins.
Do cell membranes contain genes?
No, they do not. They do contain some proteins and fats called lipids. Genes are found in the cell nucleus in the form of DNA.

What does NOT contain a structural protein?
A lipid bilayer does not contain a structural protein. Lipid bilayers are composed of lipids, such as phospholipids, arranged in a double layer that forms cell membranes and organelle membranes in cells. Structural proteins, on the other hand, provide support and shape to cells and tissues.
What is an organic compound called that is used to store energy and froms important parts of biological membranes?
Both lipids and sugars are impotent to membranes. Membranes are composed of phospholipids. They also contain glycoproteins, proteins that use sugars to help in communication between cells and identification.
What do cell membranes look like and how do they function within a cell?
Cell membranes are composed of a double layer of phospholipid molecules with proteins embedded within them. These membranes have a fluid structure that allows them to regulate the passage of substances in and out of the cell. They function as a barrier to protect the cell and also play a role in cell communication and signaling. Additionally, cell membranes contain specialized proteins and channels that facilitate the transport of molecules across the membrane.
Embedded in the phospholipid bilayer?

Do mitochondria contain proteins?
Yes, mitochondria contain proteins.

What are membranes called that contain light absorbing pigments?
Thylakoid Membranes

Are pork chops proteins?
They are not proteins, but they contain proteins.
