What functions do carrier proteins perform in active transport?
Carrier proteins of the cell membrane transport substances down their concentration gradient out of or into the cell by facilitated diffusion and active transport.
What controls which substances can move in and out of a cell?
The cell membrane regulates the movement of substances in and out of the cell.How does it do this? The phospholipid bilayer is impermeable to most substances, allowing across only small, uncharged molecules such as those of oxygen, carbon dioxide, and water. The only way for other substances to cross the membrane is via transport proteins (channel and carrier proteins). These are selective, and therefore control what enters and what leaves the cell.
What is the movement of materials across a membrane that requires energy input called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.
Move needed substances or waste materials through the plasma membrane?
transport proteins
How do substances get in and out of a cell if they are to big to pass through the cell membrane?
Do you mean how do substances move through a cell membrane if they are too big to transport by passive transport?If so, a cell uses active transport to move large particles in and out of a cell. Active transport includes endocytosis, pinocytosis, and phagocytosis.

What does active transport and facilitated diffusion have in common?
Active transport is when proteins move substances into the cell while expending energy. Facilitated diffusion is the movement of chemicals through a protein into a cell.
What proteins move need substances or waste materials through the plasma membrane?
transport proteins
How do transport proteins work?
They are used in Facilitated Diffusion, helping to transport ions, macromolecules, and other substances incapable of entering a cell by themselves to cross through the plasma membrane of the cell.

How do transport move substances across membranes?
Transport proteins change shape, much like a folding door
What is a complex molecule that is embedded in the cell membrane that helpss move substances move into and out of a cell?
Transport protein
What is the movement of materials across a membrane that requires energy input called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.
Move needed substances or waste materials through the plasma membrane?
transport proteins
What is the name of the organelle that moves proteins and other substances through the cell?
The endoplasmic reticulum are transport tubes made of membrane that move proteins and other materials through the cell, most likely sending them towards the Golgi apparatus/body.

A cell that has deformity or irregularities in transport proteins may not be able to?
Move large particles into the cell
