Biology: Cell Transport: Kahoot

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 facilitated diffusion?

Back

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

Front

What is osmosis?

Back

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

Front

What is an isotonic solution?

Back

An isotonic solution is a solution that has the same concentration of solutes as another solution, resulting in no net movement of water across the cell membrane.

Front

What happens to a cell in a hypertonic solution?

Back

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

Front

What happens to a cell in a hypotonic solution?

Back

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

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 role do receptor proteins play in cell signaling?

Back

Receptor proteins bind to signaling molecules, triggering a response inside the cell, which can include activating second messengers or changing cell permeability.
