Terms in this set (19)Does active transport require energy? Yes What is the charge of the inside of the cell? Ions move into and out of cells and because cells contain proteins that do not move across the membrane and are mostly negatively charged. What's the main difference between primary active transport and secondary active transport? -Primary is directly relied on by ATP, while secondary does not directly require ATP. How does the sodium potassium pump work? Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell. What is a uniporter? It moves molecules one at a time. Do symporters carry ions in the same direction or opposite directions? The same direction What type of carrier protein is used in coupled/co- transport? Symporter In what direction do molecules move in active transport? From low to high Draw an antiporter Which branch of active transport relies directly on ATP? Primary Transport What captures the energy from NA+ diffusion to move glucose against the concentration gradient? Sodium-Glucose Symporter What are the 3 carrier proteins associated with active transport? Uniporters, Symporters, Antiporter When cells take in a liquid through active transport, what is it called? Pinocytosis When cells take in large particles through active transport, what is it called? Phagocytosis When cells form a vesicle to take in materials, which form of transport is occurring? Endocytosis Does secondary active transport require ATP? Not directly Movement of particles through the cell membrane from high to low? Diffusion Is the sodium potassium pump an antiporter, symporter, or uniporter? Antiporter Is the sodium potassium pump a primary or secondary active transport?

In the secondary active transport, the energy is derived secondarily from energy that has been stored in the form of ionic concentration differences between the two sides of a membrane.
What is the difference between primary and active transport?The main difference between primary and secondary active transport is the source of energy used by each transport method in order to transport molecules across the cell membrane.
What is the relationship between primary and secondary active transport?The electrochemical gradients set up by primary active transport store energy, which can be released as the ions move back down their gradients. Secondary active transport uses the energy stored in these gradients to move other substances against their own gradients.
How is secondary active transport different?Unlike in primary active transport, in secondary active transport, ATP is not directly coupled to the molecule of interest. Instead, another molecule is moved up its concentration gradient, which generates an electrochemical gradient. The molecule of interest is then transported down the electrochemical gradient.
