Which organelle in a cell allows for the passage of proteins?
Nuclear Pores, Openings in the nuclear membrane allow the passing of proteins.
What type of membrane junction allows ions to pass directly from cell to cell?
Gap junctions
How to Describe the purpose of the plasma membrane?
The external, limiting lipid bilayer membrane of cells. A thin membrane around the cytoplasm of a cell. It controls passage of substances in and out of the cell. The plasma membrane allows a steady supply of nutrients to come into the cell also known as homeostasis. The plasma membrane contains proteins that span through the membrane and allow for the passage of proteins. The plasma membrane is located on the outside of animal cells or beneath the cell wall on plant cells.It is called the lipid bilayer because it is composed of two layers of fat cells organized in two sheets.LhadY Chelle p0..
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What kind of membrane junctions does a cell have?
Tight junction - impermeable junction that encircles the cell Desmosome - anchoring junction scattered along the sides of cells Gap junction - a nexus that allows chemical substances to pass between cells
What is the function of double membrane nucleus?
allows molecular proteins to enter through nuclear pores that permeate the double membrane. different than mitochondrial and chloroplast membranes because it allows whole proteins to enter. each membrane has a different molecular composition, signalling that there are two functions.
Which part allows or prevents substances to go into and out of the cell?
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
What are the special structures in the cell membrane that allows materials such as water and sugar to pass made of?
proteins
What are the special structures in the cell membrane that allows such as water and sugar to pass through made of?
proteins
Is plasma membrane premeable?
The plasma membrane is selectively permeable; it allows some substances to pass through but prevents the passage of other substances
What purpose does the membrane serve?
The membrane of a cell protects the inner part of a cell and allows the passage of substances in or out of cell.
What are the responsibilities of proteins in the cell membrane?
It depends on which protein. Most act like a door in the lipid membrane that only allows specific things through
