Match the following scenarios with the most specific type of transport used. Some choices may be used more than once. A A white blood cell enguits a bacterial cell A A paramecium swims close to some debris, wraps its membrane around the debris, and pulsit inside, creating a food Vacuole D. An amoeba wraps its cell membrane around a region of dissolved nutrients in water and pulls it inward, making a small vacuole A Phagocytosis a type of endocytosis) B. Cotransport through an antiporter C. Exocytosis D. Pinocytosis a type of endocytosis) E. Cotransport through a symporter F. Primary active transport G. Secondary active transport E ! A cardiac muscle cell requires the maintenance of a resting membrane potential before contracting This is carried out by a transport protein called the sodium/potassium pump. To function, this pump needs to be phosphorylated by ATP which drives 3 Nalons out of the cell and 2 Kelons into the cell, thus creating a more positive extracellular outside the cell environment than inside. The ATP needed is a form of what? Alteractively pumping Heons out of a guard cell in the leaves using a H. pump. the outside of the ceilis more positively charged than the inside of the cell. As a result, an electrochemical gradient is created, driving Ke Into the cell through a channel protein. This will eventially help open the pathway for CO2 to enter the leaf for photosynthesis. The movement of the K lons down its electrochemical gradient is an example of what form of transport? Helons have been actively transported out of a sucrose storage cell, causing a membrane potential where the outside of the cell is more positive than the inside of the col. Next, sucrose la photosynthesis product) can be transported into the storage cell along with the Hulons through a transport protein that can carry both Hlons and sucrose in the same direction. What is this transport called involving a transport protein that moves lons in the same direction across the membrane A root cell needs to get rid of excess No. ions. It secretes Helons out into the soil using a Holon pump, which creates an electrochemical gradient across the cell membrane Re, more positive outside, more negative inside. A transport protein that brings back into the cell down its electrochemical gradient, which drives the Nalons out of the cell through the same transporter. What type of transport is this involving a transport protein that can move lons in the Opposite direction? C After engulfing a bacterial cell, a white blood cell's Isosomes fuses with the food vacuole and digests/kills the bacterium. The food vacuole then fuses with the plasma membrane, and the broken down components are released outside the cell.

Answer 1

* a white blood cell--- A. Phagocytosis (whole cell is engulfed)

*a paramecium swims close----A. Phagocytosis (paramecium get nutrients by phagocytosis)

* an amoeba----D. Pinocytosis (dissolved nutrients is absorbed by pinocytosis)

* a cardiac muscle cell----F. primary active transport (energy is directly from ATP synthesis)

* after actively pumping ----G. secondary active transport ( energy from ATP is used to pump ions outside creating potential gradient for transporting ions inside)

* H+ ions have been ----E. Cotransport through a Symporter (a form of secondary transport where primary energy is used to transport ions together in same direction using diffusion gradient)

* A root cell------B. Cotransport through an antiporter( opposite directions)

* after engulfing bacteria -----C. Exocytosis

* forms rivet like----4.Desmosomes

* with close attachment---4.Desmosomes ( reduced cohesion causes skin abrasions)

* forms a seal all along----1.Tight junction

* pores between adjacent animal cells ----2. Gap junctions

* pores between adjacent plant cells---3. Plasmodesmata ( Gap cell is only in animals and plasmodesmata in plants)

* pores in cardiac muscles----2.Gap junctions ( Intercalated discs are gap junctions between cardiac muscle cells)

* when root epidermal cell----3. Plasmodesmata
