Cell transport

Front

What happens to eggplant cells when salt is poured on them?

Back

Water will move out of the eggplant cells and the cells will shrink.

Front

Why is passive transport called 'passive'?

Back

Because it occurs WITHOUT energy.

Front

What is the process for removing large quantities of toxins and waste from the cell?

Back

Exocytosis.

Front

What process do white blood cells use to engulf bacteria?

Back

Endocytosis.

Front

What is the term for a solution where the concentration of solutes is the SAME on both sides of a membrane?

Back

Isotonic.

Front

Define osmosis.

Back

The movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the difference between hypertonic and hypotonic solutions?

Back

Hypertonic solutions have a higher concentration of solutes compared to the cell, causing it to shrink; hypotonic solutions have a lower concentration of solutes, causing the cell to swell.

Front

What role do carrier proteins play in cell transport?

Back

They facilitate the movement of specific molecules across the cell membrane.

Front

What is the Na/K pump?

Back

A type of active transport that moves sodium ions out of the cell and potassium ions into the cell against their concentration gradients.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.
