Cell Transport

Front

What is the structure of the Cell Membrane primarily composed of?

Back

Lipids and proteins.

Front

What type of solution causes a cell to swell due to water intake?

Back

Hypotonic solution.

Front

What is an Isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is Active Transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is the role of Transport Proteins in the cell membrane?

Back

They facilitate the movement of substances across the cell membrane.

Front

What happens to a red blood cell in a Hypertonic solution?

Back

It shrinks due to water loss.

Front

Define Simple Diffusion.

Back

The passive 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 the difference between Facilitated Diffusion and Active Transport?

Back

Facilitated diffusion does not require energy and moves substances down their concentration gradient, while active transport requires energy and moves substances against their gradient.

Front

What is a Channel Protein?

Back

A type of transport protein that forms a pore in the membrane to allow specific molecules to pass through.
