"Moving with the flow" (i.e. going with the concentration gradient) is the Direction of flow
in passive transport. Show this in the diagram on the right by drawing circles to
represent molecules. You must decide a certain amount to place on the left vs. the right
side after viewing the arrow indication the direction of movement. Label the high
concentration side and low concentration side. - correct answer
Are endocytosis and exocytosis passive or active transport? - correct answerActive
Transport
At a certain time, glucose is in a high concentration outside of the cell and needs to
travel through the membrane into the cell - correct answerFacilitated diffusion
Cells lining the gut need to take in glucose, but at a certain time, the concentration of
extracellular glucose is lower the the concentration already stored in cells. - correct
answerActive transport, goes against the flow (Pump)
Charged ions are traveling through a cell membrane with the concentration gradient. -
correct answerSimple diffusion
Circle the statements below that would be TRUE about simple diffusion.
HINT : There is more than one! - correct answerA. It is a form of passive transpot
B. Molecules travel with the concentration gradient
D. It is how oxygen and carbon dioxide travel across the membrane
Give a scenario where a cell may need to perform a form of endoytosis - correct
answerTaking in food and fluids
Give a scenario where a cell may need to perform a form of exocytosis. - correct
answerRemoving waste
Sketch a phospholipid bilayer - correct answer
What is simple diffusion? - correct answerMovement from high to low concentration,
