Cellular Processes Review

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher solute concentration outside the cell than inside, causing water to move out of the cell, leading to cell shrinkage.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the movement of materials across the cell membrane with the help of special carrier proteins, without the use of energy.

Front

What is passive transport?

Back

Passive transport is the movement of materials from high to low concentration that does not require energy.

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable 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 has equal solute concentrations inside and outside the cell, resulting in no net movement of water.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration, resulting in even distribution.

Front

What is active transport?

Back

Active transport is the movement of materials against their concentration gradient, requiring energy (ATP) to do so.

Front

What role do carrier proteins play in cellular processes?

Back

Carrier proteins assist in the transport of substances across the cell membrane, particularly during facilitated diffusion.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, the solute concentration is lower outside the cell than inside, causing water to enter the cell and potentially leading to cell swelling or bursting.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of solutes.
