It is the Endoplasmic Reticulum (ER)
It is made up of protein and lipids
The two macromolecules are protein, carbs, and lipids.
They are all formed from the same elements. They are part of the cell membrane (phospholipids not just lipids). polymers of smaller subunits, i believe.

The endoplasmic reticulum (ER) is responsible for the synthesis of new membrane material in a cell. Lipids and proteins are produced by the ER and incorporated into the cell membrane to help with growth and repair.
Cell membrane, also known as plasma membrane, has been described as a sea of lipids with protein icebergs. The lipid bilayer forms the sea, while the proteins embedded in or attached to the lipid bilayer are the "icebergs" that float within it.
I am a barrier that surrounds a cell, controlling what goes in and out. I am made up of lipids and proteins, keeping the cell's contents secure. What am I?
The endoplasmic reticulum (ER) comes in twom varieties: rough ER and smooth ER.Rough ER has ribosomes attached to the cytosol side of the membrane. Ribosomes are the sites of protein synthesis so rough ER is concerned with synthesising and transporting proteins.Smooth ER lacks ribosomes and is concerned with the synthesis of some lipids.
very complicated question that is better addressed by a cell biology text but in general cell membrane itself is non-polar and allows small non-polar molecules through it also has protein that are built to selectively let in molecule based on commands from the body
Some of the lipids found in a cell membrane include phospholipids (such as phosphatidylcholine and phosphatidylethanolamine), glycolipids, and cholesterol. These lipids play a crucial role in maintaining the structure and function of the cell membrane.
The endoplasmic reticulum (ER) is the cell part that is a maze of folded membranes where proteins and lipids are produced. There are two types of ER: rough ER, which has ribosomes attached to its surface and is involved in protein synthesis, and smooth ER, which is involved in lipid synthesis.
