These proteins are attached to the membrane and their is a great variety of them. There one called the integral protein that crosses all the way through while others are triggered by biochemical reactions.These are also called carrior proteins and protein channels

Molecules move between the nucleus and the cytoplasm through?
Water soluble molecules such as protein and RNA.
What molecules that are soluble can pass through the fatty acid portion of the cell membrane unassisted?
Cholestrol
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
How do you large molecules and ions pass through the cell membrane?
Recently had a homework on the cell membrane, i do know that larger molecules that cant fit through the polar heads into the cell (like gases can...and small molecules?!) can get through only if they qualify the shape fitting of the channel protein- the one that reaches all the way from the outside to the inside of the membrane. hope this helps
Molecules move between the nucleus and the cytoplasm through?
Water soluble molecules such as protein and RNA.
What does the membrane protein do?
It acts as a facilitator to allow water-soluble subtances to pass through the cell membrane
What Molecules move between the nucleus and the cytoplasm through .?
Water soluble molecules such as protein and RNA.
How does a plasma membrane determine selectivity of molecules?
Plasma membrane possesses specific protein channels and lipid bilayer. Protein channels are of million different types, each allow a specific molecule to pass through it regarding its size, shape, charges on it, solubility, etc. Fat soluble molecules pass through lipid bilayer.
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
What molecules that are soluble can pass through the fatty acid portion of the cell membrane unassisted?
Cholestrol
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
What molecule uses energy to push molecules through the membrane of a cell?
Transport Protein
What is the definition of protein gate?
A protein gate is a pathway through a protein molecule on the plasma membrane in which ions and small molecules can diffuse in or out of a cell.
What type of molecules can permeate the plasma membrane?
Any molecule smaller than the holes in the membrane can pass through is the membrane is permeable. If the membrane is semi-permeable, then only molecules that the membrane selects can pass through. Electronegativity and existence of lipid layers are common selective traits for semi-permeable membranes.
What is the difference between protein hormones and steroid hormones and how they communicate with their target cells?
Steroid hormones arelipid-soluble and can dissolve easily into the cell membrane of the target cell to connect with receptors. Protein hormones are water-soluble and connect with receptors at the membrane because it can't diffuse through the membrane.
What is this statement most likely referring to Small nonpolar molecules may pass through this structure but others require a protein channel?
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
