passive and active transport
Explain this statement: “molecules follow a concentration gradiant"
It's all random movements, But if you have a place that you have more molocules than another place the molocules are going to have more collisons on the filled side than the empy so it is going to escape to the empty side.
Where does the energy for the process of diffusion come from?
motion of molocules-----> Kinetic energy.
do molocule go down the gradint on porpuse
No it is random motion
Explain why diffusion rate increases with the increase of temprture.
More temprture more motion in the molocules --> more mtion in the molcules more colisions(faster diffusion)
explain the diffrance between passive and active transport.
Passive= ATP needed & up gradiant
Active= no ATP needed & down gradint
