Front

What is the function of the cell membrane?

Back

The cell membrane controls what substances may enter or leave the cell, helping to maintain homeostasis.

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a form of energy used by cells.

Front

What is active transport?

Back

Active transport is the movement of solutes against the concentration gradient, requiring energy.

Front

What is passive transport?

Back

Passive transport is the movement of particles from high to low concentration without the use of energy.

Front

What is the main difference between active and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What does it mean to move substances against the concentration gradient?

Back

It means moving substances from an area of lower concentration to an area of higher concentration, which requires energy.

Front

What role does energy play in active transport?

Back

Energy is required for active transport to move substances against their concentration gradient.

Front

Can you give an example of passive transport?

Back

An example of passive transport is the diffusion of oxygen from the air into the bloodstream.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solution, such as salt in water.
