Cell Processes!

Front

What is the cell membrane?

Back

The protective outer layer that controls what enters and leaves the cell.

Front

What is diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What role do proteins play in the cell membrane?

Back

They act as gatekeepers, allowing certain substances to enter and exit, and serve as enzyme receptors.

Front

What is osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a membrane via specific transmembrane integral proteins.

Front

What are phospholipids?

Back

Molecules that make up the cell membrane, consisting of a hydrophilic head and two hydrophobic tails.

Front

What is the function of carbohydrates in the cell membrane?

Back

They play a role in cell recognition and signaling.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is concentration gradient?

Back

The difference in the concentration of a substance across a space.
