Cell Transport

Front

What is the Lipid Bilayer?

Back

The molecular structure that surrounds the cell and controls what enters and leaves the cell.

Front

What are Phosphate Hydrophilic Heads?

Back

The part of the phospholipid that is attracted to water, forming the outer layer of the cell membrane.

Front

What are Lipid Hydrophobic Tails?

Back

The part of the phospholipid that repels water, forming the inner layer of the cell membrane.

Front

What is Facilitated Diffusion?

Back

Movement of molecules across the cell membrane from an area of high concentration to low concentration, aided by proteins.

Front

What is the function of Proteins in the Cell Membrane?

Back

Proteins help transport substances across the cell membrane and act as receptors for signaling.

Front

What is the definition of Selectively Permeable Membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is Osmosis?

Back

The diffusion of water through a selectively permeable membrane.

Front

What is Active Transport?

Back

Movement of molecules across the cell membrane against the concentration gradient, requiring energy.

Front

What is the role of Cholesterol in the Cell Membrane?

Back

Cholesterol helps to stabilize the cell membrane's fluidity.

Front

What is Endocytosis?

Back

The process by which cells take in substances by engulfing them in a membrane.
