active transport Flashcards
1
Q
what is active transport?
A
movement of molecules from a region of low concentration to high concentration using energy from respiration
2
Q
what does active transport need?
A
carrier proteins (each one specific) and energy
3
Q
where is the energy needed for active transport produced?
A
from ATP
4
Q
what happens to ATP to get the energy?
A
it is hydrolysed
5
Q
what is the formula for the hydrolysis of ATP?
A
ATP + H2O -> ADP + Pi + Energy
6
Q
give an example where active transport is used
A
reabsorption of useful molecules into the blood after filtration in the kidneys
