FLASHCARD QUESTION
Front
Back
An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water across the cell membrane.
2.
FLASHCARD QUESTION
Front
What is diffusion?
Back
Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration.
3.
FLASHCARD QUESTION
Front
What is facilitated diffusion?
Back
Facilitated diffusion is a type of passive transport that allows large or polar molecules to cross the cell membrane with the help of specific proteins.
4.
FLASHCARD QUESTION
Front
What is active transport?
Back
Active transport is the movement of molecules against their concentration gradient, requiring energy, usually in the form of ATP.
5.
FLASHCARD QUESTION
Front
What role does ATP play in cellular transport?
Back
ATP provides the energy required for active transport processes, allowing cells to move substances against their concentration gradients.
6.
FLASHCARD QUESTION
Front
What is a concentration gradient?
Back
A concentration gradient is the difference in the concentration of a substance across a space, which drives diffusion and other transport processes.
7.
FLASHCARD QUESTION
Front
What is osmosis?
Back
Osmosis is the diffusion of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.
