In order for a protein to be an integral protein it would have to be what?
amphipathic
What substances would most likely require a protein to facilitate its diffusion across a cell membrane?
Quick answer: glucose Explanation: Any substance that the membrane selects against requires integral proteins to cross the membrane. B/c the lipid bilayer is selectively permeable, not all substances can pass through it by diffusion or osmosis. However, when the cell requires a substance that it's membrane does not easily allow to pass through, it must enter via the proteins in the membrane. They can either be carrier proteins or protein channels depending on the substance. One example of a substance which requires facilitated diffusion is glucose.
If you were a protein destined to reach the plasma membrane and you were making your way through the Golgi when suddenly Golgi trafficking was blocked at the trans face what would happen to you?

What ion channel is a transport protein that?
A protein channel is a transport protein that helps larger molecules, that would otherwise not be able to defuse throw the membrane of a cell, to move in or out of the cell depending on the concentration gradient.
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins

amphipathic
What happens if detergents are mix with cell membranes?
Detergents disrupt the hydrophobic interactions between an integral membrane protein and the fatty acid tails of the lipid bilayer. This removes the integral proteins from the bilayer, and since the lipid bilayer is 50% protein, this breaks it down a lot.
2 integral membrane proteins such as transport proteins are permanently attached to cellular membranes after integral membrane proteins are synthesized which organelle would aid in transporting?
Proteins are often synthesized by ribosomes on the rough Endoplasmic Reticulum.
How are proteins positioned within the membrane?
The protein is anchored into the membrane by its nonpolar region, but the protein remains moblie. To explain it more, the middle section of the protein is made of many nonpolar amino acids. This nonpolar coil fits into the nonpolar interior of the lipid bilayer allowing the protein to float in the membrane.
What would happen to the cell membrane if ribosomes are not working?
There would be no protein synthesis.
What would happen if a membrane protein were unable to bind to a signaling protein?
MESSAGES WOULD NOT BE SENT TO THE INSIDE OF THE CELL APEXXXXX
What would be found in the glomerular filtrate if the glomerular membrane were damaged?
protein
What would only be found in the glomerular filtrate if the glomerular membrane were damaged?
Protein
What would would happen if a membrane protein was unable to a signaling molecule?
Messages would not be sent to the inside of the cell.

What part of the membrane would help a large protein enter the cell?
globular proteins .
How would sugar enter a cell that has a low concentration of particles get through a cell membrane and into a cell wall?
By diffusing across the protein membrane.
