Endocytosis
When a large molecule enters a cell, it is typically transported through the process of endocytosis. This can occur via phagocytosis for solid particles or pinocytosis for liquid particles. The cell membrane surrounds the large molecule forming a vesicle that is then taken into the cell.

Large molecules can enter a cell through endocytosis, where the cell membrane folds around the molecule, forms a vesicle, and brings it into the cell. This process allows the cell to take in nutrients, signaling molecules, and other substances that are too large to pass through the membrane directly.
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
I assume that you mean "how does a large molecule enter or leave a cell, when it is too large to diffuse through the cell membrane or to be transported by transmembrane transporter proteins?" If this is the case, then the cell must actively (i.e. with energy in the form of ATP/GTP) import/export the macromolecule (large molecule) via endocytosis/exocytosis. 1. Endocytosis and 2. exocytosis are when the cell either: 1. engulfs the macromolecule in a membrane, forming a vesicle around it, which is snipped internally, leaving the vesicle and its contents inside the cell; 2. or, the macromolecule is packaged into a vesicle by the Golgi apparatus, the vesicle meets the cell membrane and fuses to it, opening up, and the contents are expelled outwards while the vesicle membrane becomes part of the cell membrane. There are many diagrams available on the internet that illustrate this process. I hope this helped.

Large carbohydrates such as glycogen, starch will not be transported in to the cell by cell membrane.
The process by which large molecules enter a cell through pouches in the membrane is called endocytosis. During endocytosis, the cell membrane forms a pouch around the molecule, encloses it, and brings it into the cell as a vesicle. This allows the cell to take in larger molecules that would not be able to pass through the membrane on their own.

Large molecules can enter cells through processes like endocytosis, where the cell membrane surrounds the molecule and engulfs it in a vesicle. This allows large molecules to be transported into the cell without crossing the lipid bilayer of the membrane.
