7LS1.2 Cell Transport

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What type of cell transport involves the movement of substances into the cell?

Back

Endocytosis is the type of cell transport that involves the movement of substances into the cell.

Front

What is exocytosis?

Back

Exocytosis is a form of active transport where substances are expelled from the cell.

Front

What is active transport?

Back

Active transport is the movement of molecules from an area of low concentration to an area of high concentration using ATP energy.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.

Front

What is pinocytosis?

Back

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

Front

What is the role of ATP in active transport?

Back

ATP provides the energy required for active transport to move substances against their concentration gradient.

Front

What is equilibrium in the context of diffusion?

Back

Equilibrium is the state reached when the concentration of molecules is equal throughout a space.
