17. After eating a salty snack like potato chips, the cells in your mouth become saturated
with salt. What happens to the cells in your mouth as they react to the elevated salt
environment?
18. If a large cell consumes or eats another smaller cell, say a tiny bacterium, which term
best describe the process by which cells eat or consume?
19. There are 2 types of diffusion (passive transport). Name these and explain how they are
different from each other.
20. Osmosis is the movement of water into and out of a cell. What type of transport is
osmosis? Also, mention what the name of the protein channel that water must go
through in order to enter or exit the cell. (Hint: Another name for water is used in the
title of this protein).
21. Describe how ATP is used in active transport. Remember the video that we watched
about the sodium/potassium pump.

17. After eating a salty snack like potato chips, the cells in your mouth become saturated
with salt. What happens to the cells in your mouth as they react to the elevated salt
environment?
Water rushes out of the cells to create a homeostatic system, causing cells to shrivel
18. If a large cell consumes or eats another smaller cell, say a tiny bacterium, which term
best describe the process by which cells eat or consume?
Phagocytosis (endocytosis)
19. There are 2 types of diffusion (passive transport). Name these and explain how they are
different from each other.
Simple and Facilitated diffusion. Simple diffusion takes place when molecules flow down the
concentration gradient across a membrane, whereas facilitated diffusion uses protein
channels to help the molecules across the membrane
20. Osmosis is the movement of water into and out of a cell. What type of transport is
osmosis? Also, mention what the name of the protein channel that water must go
through in order to enter or exit the cell. (Hint: Another name for water is used in the
title of this protein).
Osmosis is a type of facilitated diffusion because it needs the help of the aquaporin protein
channel
21. Describe how ATP is used in active transport.
ATP binds to proteins which effectively changes the shape of those proteins and allows
certain molecules to pass through the membrane.
