Is it true that the transport proteins span the cell membrane allowing the selectively permeable membrane to regulate which molecules enter an leave the cell?
false
A membrane at the boundry of every cell that acts as a selective barrier?
The membrane at the boundary of every cell that acts as a selective barrier is called the cell membrane. The cell membrane is made of compounds called proteins and lipids.
How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
They pass through channels in the cell membrane.
What molecules in the cell membrane allow for passage of substances into and out of the cell?
Cell membrane
What does the term selectively permeable mean?
If you break down the two words, selective means to only pick certain things, and permeable means to let pass through. When you talk about something being "selectively permeable", it usually refers to a cell membrane because it only lets in certain nutrients and lets out proteins and what not. I hope this answers your question.
What makes up a selectively permeable membrane?
Plasma membrane filters what the cell needs and keeps out what will harm it. this property is called selective permeability.
What roles do membrane proteins play in making the cell membrane selectively premable?
The proteinshave certain 'identifiers' attached to them, which only allow certain particles through, making it selectively permeable.
What roles do membrane proteins play in making the cell making selectively permeable?
Shidd chillen bra . you not gettin the answer because i dont know it
Is it true that the transport proteins span the cell membrane allowing the selectively permeable membrane to regulate which molecules enter an leave the cell?
false
Are the membranes in a dialysis machine permeable or selectively permeable?
The dialysis membrane is selectively permeable because it doesn't allow all cells to go through it. Think of it as a kidney. When blood is sent to the kidney, the blood cells cannot fit through the dialysis inside the kidney, but the waste and bacteria in the cells do. So, The dialysis membrane is selectively permeable.

What organelle is part of selectively permeable?
It is based on the structure of the cell membrane, which has proteins and lipids in it that make some substances impermeable to the membrane, often based on slight electrical charges and sometimes by size of the molecule or other chemical properties. Some substances require an enzyme or hormone to cross the barrier of the cell membrane, such as binding sites on cell membranes that will not allow glucose into the cell unless insulin binds with the sites, which forms a chemical bridge to allow glucose molecules to pass through the cell membrane into the cell. Without the insulin, the cell membrane is impermeable to glucose.
What does the term selectively permable mean?
it means it let some materials pass through it while block the way of others for example; the outer shell of egg
What is the propose of the cell membrane?
The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
