Membrane Transport

Front

What is embedded in the phospholipid bilayer?

Back

Proteins are embedded in the phospholipid bilayer, playing crucial roles in transport and communication.

Front

Which is NOT another name for the cell membrane?

Back

Cell wall is NOT another name for the cell membrane; it is a different structure found in plant cells.

Front

What does a cell need to transport particles by active transport?

Back

A cell needs Energy to transport particles by active transport against their concentration gradient.

Front

What does 'bilayer' mean?

Back

Bilayer means two layers, referring to the two layers of phospholipids in the cell membrane.

Front

Small, non-polar molecules like CO2 and O2 can pass through the cell membrane using what type of transport?

Back

Small, non-polar molecules pass through the cell membrane using Diffusion.

Front

What is the primary function of the cell membrane?

Back

The primary function of the cell membrane is to protect the cell and regulate what enters and exits.

Front

What is the fluid mosaic model?

Back

The fluid mosaic model describes the cell membrane as a flexible layer made of lipid molecules with embedded proteins.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What are channel proteins?

Back

Channel proteins are proteins that allow specific molecules to pass through the cell membrane.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a membrane via specific transmembrane proteins.
