Cellular Transport

Front

What is exocytosis?

Back

Exocytosis is the process of engulfing a large substance from inside the cell to move it outside of the cell, using energy.

Front

What is diffusion?

Back

Diffusion is the movement of particles through the cell membrane from areas of high concentration to areas of low concentration.

Front

What is homeostasis?

Back

Homeostasis is a state of biological balance within an organism, maintaining stable internal conditions.

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 diffusion?

Back

Facilitated diffusion is the process where particles that are too large to enter the membrane use channel proteins to cross, without the need for energy.

Front

What is active transport?

Back

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

Front

What is a concentration gradient?

Back

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

Front

What is a selectively permeable membrane?

Back

A selectively permeable membrane allows certain substances to pass while blocking others, crucial for cellular transport.

Front

What is the role of channel proteins?

Back

Channel proteins assist in the transport of substances across the cell membrane, especially for larger or charged molecules.

Front

What is pinocytosis?

Back

Pinocytosis is a form of endocytosis where the cell engulfs liquid from the surrounding environment.
