Active Transport

TermDefinition
Active Transport The process of moving molecules across a cell membrane from an area of lower concentration to an area of higher concentration, using energy.
Concentration The amount of a substance in a given volume. It refers to how much of a solute is present in a solution.
Cell Membrane A protective barrier that surrounds a cell, controlling what enters and exits the cell.
Molecule The smallest unit of a chemical compund made up of two or more atoms bonded together.
Energy The capacity to do work or produce change. In active transport, energy is required to move substances against their concentration gradient.
Gradient A difference in concentration of a substance across a space, often leading to movement from high to low concentration.
Protein Pump A type of protein in the cell membrane that actively transports molecules across the membrane using energy.
Endocytosis The process by which cells engulf substances from their environment, bringing them into the cell.
Exocytosis The process by which cells expel materials from inside the cell to the outside environment.
Transport The movement of substances across cell membranes or within the body.
Solute A substance that is dissolved in a solution.
Solution A mixture of two or more substances, typically consisting of a solute dissolved in a solvent.
Equilibrium A state in which the concentrations of a substance are balanced across a space, resulting in no net movement of molecules.
ATP (Adenosine Triphosphate) A molecule that carries energy within cells, often used in active transport processes.
Selective Permeability A property of cell membranes that allows some substances to pass through while blocking others.
Homeostasis the process by which a cell or organism maintains a stable internal environment despite external changes.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
