3.1.6 ATP

Question 1

What type of organism is plant or animal?

Answer 1

Plant autotroph
Animal heterotrophic organism

Question 2

Roles of ATP

Answer 2

Metabolic process - anabolic reaction (e.g. Condensation reaction)
Movement - muscle contraction
Active transport - molecules travelling against a concentration gradient from low to high concentration
Secretion of products from cell
Activation of molecule - by phosphorylation (add phosphate to substance to make them more reactive)

Question 3

General structure and adaptation of ATP (adenosine triphosphate)

Answer 3

3 Phosphate, ribose, Adenine
Break bond in phosphate to release energy (high energy bond)
They do not make polymer !!!
Lower activation energy (only need little energy to break the bond)
Unstable bonding - immediate energy source ( not a good energy storage)
Hydrolysis reactive

Question 4

ATP reaction equation

Answer 4

ATP + H2O —> ADP + Pi + E

Question 5

Circle process of ADP ad ATP

Answer 5

From ATP to ADP: ATP hydrolase, hydrolysis, exergonic (energy released)
From ADP to ATP : ATP synthase, condensation, Endergonic (required energy)

Question 6

Property of ATP ( structure and function)

Answer 6

Release energy in small, manageable amount and rapidly (1 bond)
One single board broke is immediate energy source = release energy instantaneously

Very water soluble : transportable (is polar can’t pass across phospholipid bilayer)
Provide energy for reaction that require it (endergonic)
Remain with in cell: always available to act as an energy source for activity or reaction in cell
Always readily available : because, when when hydrolysed for energy, rapidly the reform again
Required protein carriers to cross the membrane

Question 7

ATP vs DNA

Answer 7

3 Phosphate group vs 1 phosphate group
Ribose sugar vs deoxyribose sugar
Base A vs various and difference

Question 8

Exam Q : describe how ATP is resynthesised in the cell

Answer 8

Adding energy and a inorganic phosphate by condensation in endergonic process
