Cell Membrane and Transport

Front

What is ATP used for in cellular processes?

Back

ATP is a form of energy used for Active Transport.

Front

What is the process called when molecules move from high concentration to low concentration through a carrier protein?

Back

This process is called Passive Transport.

Front

What is osmosis?

Back

Osmosis is the movement of water across a membrane.

Front

Define Selective Permeability.

Back

Selective Permeability is the ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What type of transport requires energy to move solutes against the concentration gradient?

Back

Active Transport requires energy to move solutes against the concentration gradient.

Front

What is the main function of the cell membrane?

Back

The main function of the cell membrane is to protect the cell and regulate what enters and exits.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.

Front

What role do carrier proteins play in transport?

Back

Carrier proteins facilitate the movement of specific molecules across the cell membrane.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances.

Front

What is a concentration gradient?

Back

A concentration gradient is the difference in the concentration of a substance across a space.
