Cell Membrane Practice

Front

What is the main component of the cell membrane?

Back

Phospholipid

Front

What type of movement uses proteins that act like pumps to move sodium and potassium through the cell membrane?

Back

Sodium potassium pump

Front

What type of movement goes from low to high concentration?

Back

Active transport

Front

What is the term for a solution that has lower concentration outside than inside the cell, causing the cell to swell?

Back

Hypotonic

Front

What type of transport does not require energy and moves molecules from high to low concentration?

Back

Diffusion

Front

What is the process called when water moves across a semipermeable membrane?

Back

Osmosis

Front

What type of transport involves the use of proteins to help move molecules across the membrane without energy?

Back

Facilitated diffusion

Front

What is the role of cholesterol in the cell membrane?

Back

To maintain fluidity and stability of the membrane.

Front

What are the two main types of transport across the cell membrane?

Back

Active transport and passive transport.

Front

What is the function of membrane proteins?

Back

To facilitate transport, act as receptors, and provide structural support.
