Cells in Action

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is a molecule that carries energy within cells, allowing them to perform various functions.

Front

What is glycolysis?

Back

Glycolysis is the first step in cellular respiration, where glucose is broken down to produce ATP.

Front

What is endocytosis?

Back

Endocytosis is the process by which a cell membrane surrounds a particle and encloses it in a vesicle to bring it into the cell.

Front

What is active transport?

Back

Active transport is the movement of particles through proteins in the cell membrane against the direction of diffusion, requiring energy.

Front

What is passive transport?

Back

Passive transport is the diffusion of particles through proteins in the cell membrane from areas of high concentration to areas of low concentration without using energy.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane facilitate the transport of substances in and out of the cell, including active and passive transport.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules through a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the cell membrane.

Front

What is the difference between diffusion and osmosis?

Back

Diffusion is the movement of particles from high to low concentration, while osmosis specifically refers to the movement of water.
