Active Transport Flashcards
When do we use active transport
When molecules want to be transported in to and out of the cell against the concentration gradient
What is needed for active transport to work
Additional energy
Where dose the energy come from
ATP
ATP is what
An energy stored molecule made in cellar respiration
What is ATP stood for
Adenosine triphosphate
Adenosine triphosphate can be broken down into
Adenosine diphosphate and phosphate
When the substance is broken down what happens
Energy is released
The symbol equation is
ATP > ADT+P i +energy
Pi means
In organic phosphate ion
Each carrier protein is
Specific for one or a few molecules
ATP binds to what
Carrier proteins
The proteins change shape and energy from the breakdown of ATP is used for
Transporting the molecules across the concentration gradient
As the molecule are Telstar the carrier proteins go to
A normal shape and allow more molecule to be taken in
