04. CELLULAR TRANSPORT JEDI TRAINING

Front

What is endocytosis?

Back

Endocytosis is a form of active transport where cells engulf substances from the outside environment, bringing them into the cell.

Front

What is exocytosis?

Back

Exocytosis is a form of active transport where cells expel materials to the outside environment.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move substances across the cell membrane without energy.

Front

What is diffusion?

Back

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

Front

What is osmosis?

Back

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

Front

What is a protein pump?

Back

A protein pump is a type of active transport mechanism that moves ions or molecules against their concentration gradient using energy.

Front

What is the difference between active and passive transport?

Back

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

Front

What role do carrier proteins play in cellular transport?

Back

Carrier proteins assist in the transport of substances across the cell membrane, either through facilitated diffusion or active transport.

Front

What is the significance of the concentration gradient in cellular transport?

Back

The concentration gradient is crucial as it drives the movement of substances during passive transport, moving from high to low concentration.

Front

What is the role of ATP in active transport?

Back

ATP provides the energy required for active transport processes, allowing substances to be moved against their concentration gradient.
