Active Transport Flashcards
1
Q

A
Release energy
2
Q
What type of diffusion gradient does AT maintain?
A
It maintains a steep diffusion gradient
3
Q
What happens if the mitochondria is damaged?
A
AT will shut down.
4
Q
Definition of AT?
A
Movement of a molecule/ion against the concentration gradient (low to high), uses carrier molecules on the membranes. REQUIRES ENERGY!!!!!!!!!!
5
Q
What does AT require that osmosis and diffusion do not?
A
ENERGY
6
Q
What does AT do?
A
Drags in and throws out ions
7
Q
Give an example of AT in humans?
A
digestion of food in the small intestine. Carbs are broken down into glucose. The glucose is absorbed by active transport into the villi, passed into the bloodstream and.
