Proteins are MUCH tinier (by a million times) than a cell.
proteins
DNA that is not being "used" by the cell is wrapped up around proteins called histones.

Through specialized carrier proteins in the cell membrane.

through active transport, as transport proteins are needed to fit them through the phospholipid bilayer. this requires energy, as the proteins are doing a lot of work to move the large molecules.
Ribosomes are the cell organelles that assemble proteins. They function as factories to produce usable proteins for a cell.
There are two kinds of proteins in a cell membrane: peripheral PROTEINS OR trans membrane proteins. Cell membranes are able to perform various functions only because of different membrane protein functions. Most of the membrane proteins have alpha helix structure.
It wraps the DNA around proteins, and then coils further forming a compact fiber.
Proteins do not pass through cell membranes freely because they are large molecules that cannot easily fit through the membrane's lipid bilayer. Instead, proteins are typically transported into or out of cells through specific channels or transport proteins in a process called facilitated diffusion or active transport.
The proteins that control reaction in a cell are enzymes.
Ribosomal proteins are synthesized in the cytoplasm of the cell.
