Cell Transport Review

Front

What is diffusion in the context of cell transport?

Back

Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What type of transport does diffusion represent?

Back

Passive transport.

Front

What happens to a cell when it is placed in a hypertonic solution?

Back

The cell will shrink due to water moving out of the cell.

Front

What is the primary characteristic of active transport?

Back

Active transport involves the movement of molecules against their concentration gradient, requiring energy.

Front

Define active transport in terms of concentration gradients.

Back

Active transport is the movement of particles from an area of lower concentration to an area of higher concentration.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the role of the cell membrane in transport processes?

Back

The cell membrane regulates the movement of substances in and out of the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, causing the cell to swell.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing the cell to shrink.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.
