Cell Transport Practice

Front

What is the general name for movement of substances across cell membranes without the need for energy input?

Back

Passive transport.

Front

What is the term for particle movement from an area of lower concentration to an area of higher concentration?

Back

Active transport.

Front

What type of transport involves particles moving against the concentration gradient?

Back

Active transport.

Front

In which situation would a cell most likely shrink?

Back

When placed in a solution containing a high salt concentration.

Front

What is the process called that is used to move very large proteins into the cell?

Back

Endocytosis.

Front

What is the primary difference between passive transport and active transport?

Back

Passive transport does not require energy, while active transport does.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What happens to a cell in a hypotonic solution?

Back

The cell swells and may burst due to water entering the cell.

Front

What is the role of carrier proteins in facilitated diffusion?

Back

Carrier proteins help transport substances across the cell membrane without using energy.

Front

What is exocytosis?

Back

The process by which a cell expels materials in vesicles.
