Cell Transport Vocab

Front

What is Exocytosis?

Back

Exocytosis is the process by which a cell forms a vesicle around unwanted particles and expels it out of the cell.

Front

True or False: In Active Transport, energy is not required.

Back

False. Active transport requires energy to move substances against their concentration gradient.

Front

What is a key characteristic of Active Transport?

Back

Active transport requires energy to move substances from low to high concentration.

Front

What is Facilitated Diffusion?

Back

Facilitated diffusion is the movement of materials into and out of the cell with the use of proteins but without the use of energy.

Front

Where is there a low concentration of dye in a cup?

Back

At the bottom of the cup.

Front

Define Passive Transport.

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, typically moving down the concentration gradient.

Front

What is Osmosis?

Back

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

Front

What is the role of proteins in Facilitated Diffusion?

Back

Proteins help transport substances across the cell membrane without using energy.

Front

What does it mean to move substances down the concentration gradient?

Back

It means moving substances from an area of higher concentration to an area of lower concentration.

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 and moves substances down their concentration gradient.
