Active Transport Flashcards
1
Q
What happens during active transport?
A
Salts or ions are pumped from an area of LOW concentration to an area of HIGHER concentration
2
Q
Does this process require energy released by the cell?
A
Yes
3
Q
What are 2 examples where active transport would be used?
A
~ Nitrate ions must be actively transported to the inside of plant cells
~ Glucose is actively transported from the small intestine into the blood
4
Q
What 5 factors affect active transport?
Note: Any factor that affects the rate of respiration will affect the rage of active transport
A
~Needs energy which is released in respiration
~Glucose concentration
~Oxygen
~Temperature
~Toxic substances (cyanide stops respiration)
5
Q
What is active transport?
A
When the concentration of a material is lower outside the cell
