Cell Transport & Homeostasis

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration without the use of a protein channel.

Front

What is an isotonic solution?

Back

An isotonic solution is a solution or environment surrounding a cell that has the same amount of solutes and the same amount of water as the cell.

Front

What is a hypotonic solution?

Back

A hypotonic solution is a solution or environment surrounding a cell that has less solutes and more pure water than the cell.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is a monosaccharide?

Back

A monosaccharide is the simplest form of carbohydrate, consisting of a single sugar molecule, such as glucose or fructose.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via a protein channel.

Front

What is 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 a hypertonic solution?

Back

A hypertonic solution is a solution that has a higher concentration of solutes compared to the inside of a cell, causing the cell to lose water.

Front

What is the role of protein channels in cell transport?

Back

Protein channels facilitate the movement of specific molecules across the cell membrane, aiding in processes like facilitated diffusion.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their concentration gradient.
