Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
What materials go in and out of an organism's cells through?
The cells go through the cell's membrane
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.
Why doesn't protein pass through the cell membrane?
Cell membrane consist of phosholipid layres and have small pores in it aproximately of the size of 80nm which allows only those molecules which are smalles then this pore size. So it is semi or selective permeable.
Where does oxygen go after it passes through the the cell membrane?
The Mitochondria

How does CO2 cross the cell membrane?
No, carbon dioxide does not need a transport protein to cross the cell membrane. It can pass through a membrane by diffusion.
What materials go in and out of an organism's cells through?
The cells go through the cell's membrane
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins
What type of molecules can easily go through your cell membrane or are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
What types of molecules can easily go through your cell membrane are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
How can water go through the cell membrane when it is polar?
Because it is a small molecule, water can diffuse through the cell membrane.
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.

After the protein is made where is it sent?
It depends on the function. It can go anywhere within the body. It can enter the blood stream, be excreted through glands, become part of the cell membrane, part of the cell,etc.
Where does oxygen go after it passes through the the cell membrane?
The Mitochondria
How do properties of lipid help explain the structure of a cell membrane?
Lipids have hydrophilic (water loving) heads, and hydrophobic (tails). Therefore, the tails face one another while the heads face out to the water. And if particles must pass through the cellular membrane that are hydrophilic they must go through protein channels within the cell membrane.
