Cellular Transport Flashcard

Front

What is the type of cellular transport that does not require energy?

Back

Passive Transport

Front

Which organelle is responsible for maintaining homeostasis in a cell?

Back

Cell Membrane

Front

What happens to water in an isotonic solution?

Back

Water will diffuse into and out of the cell.

Front

Name two examples of molecules that can diffuse through the cell membrane.

Back

Oxygen and carbon dioxide.

Front

What is the function of the sodium-potassium pump?

Back

It moves sodium and potassium in opposite directions from a low concentration to high.

Front

What is active transport?

Back

The movement of molecules across a cell membrane using energy, typically against a concentration gradient.

Front

Define diffusion in the context of cellular transport.

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 diffusion of water across a selectively permeable membrane.

Front

What is the role of the cell membrane in cellular transport?

Back

The cell membrane regulates what enters and exits the cell, maintaining homeostasis.

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes outside the cell than inside, causing water to move out of the cell.
