Cell Membrane and Transport

Front

What is the function of a cell’s selectively permeable membrane?

Back

It regulates what materials enter and leave the cell.

Front

Where can PROTEINS be found when part of a plasma membrane?

Back

All of the above (On the outside, inside, embedded partway, and embedded the whole way through the membrane).

Front

What molecule is a key component of the cell membrane?

Back

Phospholipid.

Front

What type of transport involves the movement of molecules across a membrane without energy?

Back

Facilitated diffusion.

Front

Osmosis is the movement of _____ across a membrane.

Back

Water.

Front

What is the primary role of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

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

Back

Passive transport and active transport.

Front

What is passive transport?

Back

Movement of substances across a cell membrane without the use of energy.

Front

What is active transport?

Back

Movement of substances against their concentration gradient, requiring energy.

Front

What is a phospholipid?

Back

A molecule that makes up the cell membrane, consisting of a hydrophilic head and two hydrophobic tails.
