What are the three types of passive transport?

Back

Diffusion, Osmosis, Facilitated Diffusion

Front

A solution where the concentration of a sugar solution is lower outside the cell than inside the cell, is a ______________ solution.

Back

Hypotonic

Front

Molecules that are too large to be moved through the cell membrane can be transported OUT OF the cell by

Back

Exocytosis

What is structure B?

Carbohydrate chain

Front

Define diffusion.

Back

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

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

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

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells and may burst due to water entering the cell.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes outside the cell than inside.
