lipids and proteins
The main organic materials that make up the plasma membrane of a cell are lipids and proteins. Lipids, such as phospholipids and cholesterol, form the basic structure of the membrane, providing a barrier to the cell's interior. Proteins are embedded within the lipid bilayer and facilitate various functions, including transport of molecules and cell signaling.
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
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.
The cellular reaction of oxygen (O2) and glucose (C6H12O6) is know as aerobic respiration. This reaction takes place in a cell's mitochondria.
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.

Proteins in the cell membrane can act as transporters or channels, aiding in the facilitated diffusion of specific molecules across the membrane. These proteins provide a passageway for the molecules to move across the membrane by utilizing their specific structure and function. This process helps regulate the movement of molecules in and out of the cell.
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.
Phospholipids lay to the foundation. They are type of lipids.
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.
The cellular reaction of oxygen (O2) and glucose (C6H12O6) is know as aerobic respiration. This reaction takes place in a cell's mitochondria.
Both serve to transport molecules across cell membranes and both make use of proteins embedded in cell membrane in order to move these molecules.
Phospholipids and proteins are the two main types of molecules that make up the cell membrane. Phospholipids form a lipid bilayer that serves as the basic structure of the membrane, while proteins are embedded within this lipid bilayer and help to carry out various functions such as transport, signaling, and support.
