Biology: Cell Transport: Kahoot

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on concentration gradients.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy, often in the form of ATP.

Front

Define osmosis.

Back

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

Front

What is the sodium-potassium pump?

Back

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

Front

What is endocytosis?

Back

Endocytosis is a process by which cells engulf substances from their external environment, bringing them into the cell.

Front

What is diffusion?

Back

Diffusion is the passive movement of particles from an area of higher concentration to an area of lower concentration until equilibrium is reached.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses carrier proteins to help move substances 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 it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

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

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space, driving the movement of particles.
