What 2 kinds of molecules are important in making cell membranes?
A phosphate group and a lipid (to form a phospholipid).
Which two kinds of molecules combine to form cell membranes?
Lipids and proteins are two kinds of molecules that combine to form cell membranes. Lipids make up the majority of the membrane structure, creating a phospholipid bilayer, while proteins are embedded in the lipid bilayer and play various roles in cell function.
Does biological molecules proteins and lipids have cell membranes?
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
What is the substance found in animal cell membranes?
The substance found in animal cell membranes is primarily phospholipids. These molecules have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tail, which arrange themselves in a bilayer to form the structure of the cell membrane. Other components like cholesterol and proteins are also present in cell membranes.
What self antigens is found on cell membranes?
Major histocompatibility complex (MHC) proteins, also known as human leukocyte antigens (HLAs), are self antigens found on cell membranes. These proteins play a key role in presenting foreign antigens to the immune system for recognition.
What are proteins found in cell membranes that transport large molecules?
carrier molecules
What 2 kinds of molecules are important in making cell membranes?
A phosphate group and a lipid (to form a phospholipid).
Where are transport proteins located?
Transport proteins are typically located in cell membranes, where they facilitate the movement of molecules across the membrane. These proteins can be found in both the plasma membrane of the cell and the membranes of intracellular organelles such as the mitochondria and endoplasmic reticulum.

What is the cell membrane found in the animal?
The main component of cell membranes are phospholipids. There are also proteins, carbohydrates and cholesterol molecules found within the membrane.
How are the function of ribosomes and why cell need them?
Other proteins support cell functions and are found embedded in membranes. Proteins even make up most of your hair. When a cell needs to make proteins, it looks for ribosomes.
Why Proteins do not pass through cell membranes?
Hydrophilic proteins.
Can you find protein in your body?
Every cell has proteins. All genes ultimately code for proteins. Proteins are involved in virtually all (if not all) cell processes. Proteins are found in the cell membranes, in the cytosol, in organelles, in the bloodstream, basically everywhere.
Where do you find membrane proteins in biological systems?
Membrane proteins are found embedded within the lipid bilayer of cell membranes in biological systems.
What Flattened membranes that package proteins?
this is a cell
