10 Questions
Which process requires an input of energy to transport molecules from lower to higher concentration?
Active transport
What is responsible for active transport in maintaining a proper balance of ions and molecules?
Sodium-potassium pump
What type of cellular transport mechanism involves substances crossing the cell membrane without the input of energy?
Osmosis
In active transport, the movement of materials occurs in which direction?
From lower to higher concentration
Which of the following is an example of active transport?
Vesicle-mediated transport
What mechanism involves the Sodium-Potassium pump?
Active transport
Which process describes substances moving through ion channels without energy input?
Facilitated diffusion
What type of cellular transport allows substances to cross the cell membrane from higher to lower concentration without energy input?
Osmosis
Which of the following is NOT a type of active transport mechanism?
Simple diffusion
What do active transport and passive transport have in common?
Both happen across the cell membrane.
Explore the process of vesicle-mediated transport, where vesicles fuse with the cell membrane to release or transport substances in and out of cells. Learn about endocytosis, a process where cells ingest external fluid, macromolecules, and large particles. Discover the types of vesicle-mediated transport mechanisms.
