Cellular Transport

Front

What is passive transport?

Back

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

Front

What is exocytosis?

Back

Exocytosis is the process of engulfing a large substance from inside the cell and moving it outside, which requires energy.

Front

What is a semi-permeable membrane?

Back

A semi-permeable membrane allows certain molecules or ions to pass through by diffusion while blocking others.

Front

What is active transport?

Back

Active transport is the movement of particles against the concentration gradient, from low to high concentration, using energy (ATP).

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a cell membrane from an area of high water concentration to an area of low water concentration.

Front

What is facilitated transport?

Back

Facilitated transport is a type of passive transport that uses protein channels to help move molecules across the cell membrane.

Front

What is endocytosis?

Back

Endocytosis is the process of taking in large substances by engulfing them with the cell membrane, which requires energy.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration without the use of energy.

Front

What is homeostasis?

Back

Homeostasis is the process by which cells maintain a stable internal environment despite changes in external conditions.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance across a space, which drives the movement of particles.
