FLASHCARD QUESTION

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a process by which substances cross membranes with the assistance of special proteins, without the expenditure of energy.

2.

FLASHCARD QUESTION

Front

Which type of molecules typically require facilitated diffusion to cross the cell membrane?

Back

Large or polar molecules, such as glucose and ions, typically require facilitated diffusion to cross the cell membrane.

3.

FLASHCARD QUESTION

Front

What role do receptor proteins play in cell signaling?

Back

Receptor proteins bind to signal molecules, triggering a response within the cell, which can include changes in gene expression or cellular activity.

FLASHCARD QUESTION

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

5.

FLASHCARD QUESTION

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing the cell to shrink.

6.

FLASHCARD QUESTION

Front

What is the function of the sodium-potassium pump?

Back

The sodium-potassium pump actively transports sodium ions out of the cell and potassium ions into the cell, maintaining the electrochemical gradient.

7.

FLASHCARD QUESTION

Front

What is osmosis?

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
