4.4 Active Transport Flashcards
1
Q
What are the 3 components of ATP
A
Triphosphate chain
Adenine
Ribose sugar
2
Q
What is difference between ATP and ADP?
A
ADP has 1 less phosphate than ATP
3
Q
What does ATP stand for?
A
Adenosine triphospahate
4
Q
How is energy released from ATP?
A
By a phosphate being hydrolysed out of its bond
5
Q
Where and from which processes is ATP released from?
A
The mitochondria
Respiration
6
Q
Which protein does active transport use?
A
Carrier proteins
7
Q
How does ATP move molecules against the concentration gradient?
A
ATP loses a phosphate, this bonds to the carrier protein giving it energy to change shape to allow molecules out
8
Q
What are the limiting factors of active transport?
A
Number of mitochondria
Amount of ATP
Rate of respiration
Number of carrier proteins available
