What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
How do molecules that are too large to cross the membrance enter into the cell?
If the large molecule won't pass through the membrane by diffusion, it might be dragged through the membrane by "endocytosis".
Large molecule made up of amino acids?
protein !
What part of the cell is like a gate?
In this analogy, the cell membrane is like a wall, keeping what's in the cell inside, and what is outside of the cell out. However, there are "gates" called receptors. Receptors are large protein molecules embedded in the membrane, with one end outside and one end inside. Different gates, or receptors, permit certain things to enter. For example a glucose receptor lets glucose enter the cell. When a glucose molecule passes a glucose receptor, the glucose molecule is attracted to the receptor by an electric charge. It then binds to the receptor, but now the balance of the charges in the protein molecule has been changed, so the protein molecule changes shape. When it changes shape, it pulls the glucose into the cell and then lets go of the glucose. Now the protein is free to return to its original shape, and the glucose is inside the cell.
What is the movement of large substances out of the cell?
any large molecule is moved out of the cell from the cell membrane
Which parts of cell membrane would help a large protein molecule enter the cell?
Globular Proteins
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.

What does facilitated diffusion?
A transport protein, a large polar molecule, a semi-permeable membrane and a concentration gradient.

Would help large carbohydrate molecule enter the cell?
Large carbohydrates such as glycogen, starch will not be transported in to the cell by cell membrane.
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
Large molecules are surrounded by the cell membrane and enter the cell?
A large molecule that can not enter the cell through myosis enters the cell through by endocytosis. Endocytosis is an example of active transport.
How do molecules that are too large to cross the membrance enter into the cell?
If the large molecule won't pass through the membrane by diffusion, it might be dragged through the membrane by "endocytosis".
