ATP Flashcards
What happens during resperation
The energy stored in glucose isnt released directly. Instead the energy released is used to form ATP.
What does ATP stand for
Adenosine triphospate
What is the process from glucose to energy
Glucose—> ATP—> Energy
resperation hydrolysis
What is ATP made up of
Adenine
Ribose sugar
3 phospate groups
What does nucleotide derivative mean
That its a modified version of a nuclotide
What are the similarities of DNA and ATP
Both contain phospate
Can both contain adenine
Both have 3 components
What are the differences between DNA and ATP
DNA doesn’t always have adenine whereas ATP always does
DNA only has 1 phospate group however ATP has 3
DNA has deoxyribose sugar however ATP has ribose sugar
Where is the energy stored in
The energy released from ATP is stored in the bond between the 2nd and 3rd phosphate
When the bond in hydrolysed then energy is released
WHAT IS ENERGY NOT
IT ISNT CREATED OR DESTROYED
What does ATP hydrolysis form
The high energy bond is broken down using hydrolysis to form Adenosine Diphospate (ADP) and an inorganic phosphate (Pi)
What enzyme does ATP hydrolysis require
ATP hydrolase
What is the chemical reaction for ATP hydrolysis
ATP+water–> ADP+Pi+energy
What are the 2 processes where ATP is made
Photosynthesis
Resperation
How is ATP made
It is made from ADP+Pi via a condensation reaction
What enzyme does this require
ATP Synthase
What is the chemical reaction for making ATP
ADP+Pi–>ATP+H20
Why is ATP used in many biological processes
Energy is released in small usuable amounts
Adds phosphate to molecules to make them more reactive lowering activation energy
Involves a single step reaction to release energy
When glucose is respired what happens to the energy when not incorporated into ATP
its released as heat
Give 2 ways in which the hydrolysis of ATP is used in cells
To provide energy for other reactions
To phosphorylate other compounds to make them more reactive
Describe how ATP is resynthesised into cells
From ADP and phosphate by ATP synthase during respiration or photosynthesis
Give 2 functions of ATP
To bind the amino acids to tRNA
To bind amino acids to one another.
