Stores stuff Period: Name: Cellular transport Quiz Period: Short Answer: 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.
