Cell Membrane Flashcard 1

Front

Most of the cell membrane is made of...

Back

Lipids

Front

In this image, the cell is using which type of molecular transport?

Back

Endocytosis

Front

The cell below is in a _____________ solution.

Back

Hypotonic

Front

Movement of particles from high to low concentration.

Back

Passive Transport

Front

Which type of Passive Transport is being represented in this picture?

Back

Facilitated Diffusion

Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and leaves.

Front

Define Osmosis.

Back

The movement of water molecules through a selectively permeable membrane from a region of low solute concentration to a region of high solute 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.

Front

What does Isotonic mean?

Back

A solution with the same concentration of solutes as another solution, resulting in no net movement of water.

Front

What is the role of proteins in the cell membrane?

Back

Proteins help transport substances across the membrane and act as receptors for signaling.
