What else can I help you with?
In order for a protein to be an integral protein it would have to be what?
An integral protein must be firmly embedded within a cell membrane, spanning across it from one side to the other. This positioning allows integral proteins to have both an extracellular and intracellular domain, contributing to their crucial role in cell signaling and transport.
What components of the plasma membrane of an animal cell would you find at its innermost surface directly exposed to the cytoplasm?
At the innermost surface of the plasma membrane of an animal cell, you would find peripheral proteins, integral proteins, and phospholipids directly exposed to the cytoplasm. These components help regulate the entry and exit of molecules, facilitate cell signaling and communication, and maintain the structural integrity of the membrane.
What type of amino acid side chain would you expect to find on the surface of a protein embedded in a cell membrane?
You would expect to find hydrophobic amino acid side chains on the surface of a protein embedded in a cell membrane. These hydrophobic side chains interact favorably with the hydrophobic lipid bilayer of the membrane, helping the protein to stay anchored in the membrane.
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.
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins

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.
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.
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?

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

Messages would not be sent to the inside of the cell.
