What is the primary difference between regular active transport and passive transport?
Active transport moves molecules, passive does not
Active transport happens inside cells, passive outside
Active transport involves proteins, passive doesn't
Active transport requires energy, passive does not
What molecules are used to fuel the process of active transport?
DNA
ADP
RNA
ATP
Sort the following
Involves the use of a protein pump
Involves solutes moving through a protein channel without the use of energy
The goal is to reach dynamic equilibrium
Involves the movement of water
Moves molecules against the concentration
Involves the movement of solutes from areas of low concentration to areas of high concentration
Involves the movement of solutes from areas of high concentration to areas of low concentration
Does not require energy
Simple diffusion
Facilitated diffusion
Osmosis
"Regular" active transport
What is the meaning of endocytosis in the context of active membrane transport?
Process where the cell engulfs materials outside of the cell
Process where the cell's membrane is repaired
Act of transporting proteins within the cell
Action of expelling materials out of the cell
Why is ATP needed in regular active transport?
To provide energy for cellular respiration
To facilitate diffusion across the membrane
To provide energy for moving substances against concentration gradient
To aid in the duplication of DNA molecules
In what process do cells expel waste materials or secrete substances?
Endocytosis
Regular active transport
Osmosis
Exocytosis
Identify the type of active transport each of the following fall under.
