no, but active transport on the other hand, does require transport proteins to transport the large molecules into the cell.
Carbohydrates cannot pass directly through the cell membrane. some important molecules are too large to pass through the cell membrane
To make proteins so the cell can function.
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
Transport proteins allow nutrients to enter and leave cells. Transport proteins are peppered throughout the cell membrane. Most molecules need the transport proteins to enter or leave the cell, but it's possible for some molecules, like water, to diffuse through the membrane by osmosis.
Other proteins support cell functions and are found embedded in membranes. Proteins even make up most of your hair. When a cell needs to make proteins, it looks for ribosomes.
