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 2 main group of organic materials make up the plasma membrane of a cell?
Lipids and proteins
What part of cell controls movement of molecules in and out of cell?
The cell membrane controls what enters and leaves the cell. There are protein channels within the lipid bilayer (membrane) of the cell. There are carbohydrate chains that hang off of the protein channels that identify each particle around the cell to make sure its what the cell needs, if not it wont let it in.
What is the outermost component of all cells?
The outermost living part of a cell is the cell membrane. The cell membrane regulates what comes into the cell and what goes out of the cell. It is composed of a double layer of phospholipids and proteins.
What membrane bound organelle uses oygen and organic molecules to make ATP?
The cellular reaction of oxygen (O2) and glucose (C6H12O6) is know as aerobic respiration. This reaction takes place in a cell's mitochondria.
What kind of molecules make up cell membrane?
brain cells
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.
Name the 3 organic compounds that make the cell membrane?

What 2 main group of organic materials make up the plasma membrane of a cell?
Lipids and proteins
What type of molecules cannot pass through the lipid bilayer of a cell membrane through diffusion?
Ions cannot pass through such as Na+ and K+ - these require membrane proteins. Some larged polar molecules cannot cross either - such as glucose and sucrose - these also require membrane proteins.
What molecules make up the bi layer of a cell membrane?
Phospholipids lay to the foundation. They are type of lipids.
What parts make up the cell membrane?
Most of the cell membrane are made up of proteins and phospholipids. The phospholipids make up the basic cell body, with tiny holes scattered around. It is not a solid piece. The proteins gather around the tiny holes and help move molecules in and out of the cell.
What 2 molecules make up the cell membrane?
The plasma membrane is flexible and is made up of organic molecules called lipids and proteins .
What part of cell controls movement of molecules in and out of cell?
The cell membrane controls what enters and leaves the cell. There are protein channels within the lipid bilayer (membrane) of the cell. There are carbohydrate chains that hang off of the protein channels that identify each particle around the cell to make sure its what the cell needs, if not it wont let it in.
How are diffusion and active transport similar?
Both serve to transport molecules across cell membranes and both make use of proteins embedded in cell membrane in order to move these molecules.
What is the outermost component of all cells?
The outermost living part of a cell is the cell membrane. The cell membrane regulates what comes into the cell and what goes out of the cell. It is composed of a double layer of phospholipids and proteins.
