CELL MEMBRANE DAY TWO (A)
Objective: Today we will compare and contrast the three forms of transport across a cell membrane.
Warm Up: Osmosis Worksheet
Cell Transport
Notes

Describe these 3 types of movement across cell membranes.
1. simple diffusion
2. facilitated diffusion
3. active transport

Passive transport does _______ require additional energy & moves materials from ________ to
_________ concentration.

Give 2 examples of passive transport in cells.

___________ diffusion is a type of __________ transport because energy is NOT required.

Facilitated diffusion uses _____________ proteins to help move materials from _________ to
__________ concentrations.

Name 2 materials that move into or out of cells by facilitated diffusion.

Name 2 types of transport proteins found in cell membranes.

Describe channel proteins.

How do carrier proteins help move materials across a cell membrane?

Channel proteins have an opening or ___________ through which molecules can passively move by
_____________ diffusion.

Do all carrier proteins extend across the cell membrane? _____

Explain how these carrier proteins move materials across the membrane.

Some carrier proteins can change ________ to move materials across the cell membrane.

__________ transport requires additional energy to move materials.

Active transport uses cellular energy known as _________.

Active transport moves materials AGAINST the concentration gradient or from _________ to
___________ concentration.

The _______________ pump is an example of active transport.

Moving very large particles out of the cell is called _____________.

In exocytosis, wastes are moved out of the cell in ___________ that fuse with the cell membrane.

__________ involves moving large particles into the cell.

Taking in large liquid droplets is called ____________ or "cell drinking".
