Front

What is active transport?

Back

Active transport is the process by which cells use energy to move ions or molecules against their concentration gradient, from an area of lower concentration to an area of higher concentration.

Front

What is passive transport?

Back

Passive transport is the movement of ions or molecules across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration until equilibrium is reached.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the cell membrane, releasing their contents outside the cell.

Front

What is endocytosis?

Back

Endocytosis is the process by which a cell takes in materials by engulfing them in a vesicle formed from the cell membrane.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses transport proteins to help move molecules across the cell membrane.

Front

What is the sodium-potassium pump?

Back

The sodium-potassium pump is a type of active transport mechanism that moves sodium ions out of the cell and potassium ions into the cell, crucial for maintaining cellular function.

Front

What happens when a cell is in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing the cell to shrink.

Front

What happens when a cell is in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing the cell to swell and potentially burst.
