Active and Passive Transport
By: Madison and Luisa
Hi, My name is Jerry. I am a motor protein.
This is my friend Albert and his siblings. They are proteins inside of a vesicle.
Albert needs to get home. He cannot get there on his own so I must help him.
His home is all the way across the cell and through the membrane.
The cell is like a town and the membrane is the edge of the town.
To get him home we must take the microtubule trolley car.
To make the trolley car move, Jerry must pay with ATP. ATP is like money.
The distance the car travels depends on how much ATP is payed.
Along the way the trolley car stops and Jerry must insert more ATP so that the trolley car will keep moving.
Just as they were getting close to the membrane, the trolley car stopped.
Once Jerry paid some more ATP, the trolley lurched forward and started to move again.
They finally arrived at the membrane. They hopped off and began to walk towards the membrane.
Jerry began to get back into the trolley as the vesicle began to pop. Albert and his siblings then went through the membrane.
Thank you for watching!
