ATP

Question 1

What does ATP stand for?

Answer 1

Adenosine Triophosphate

Question 2

What is ATP?

Answer 2

• nucleotide derivative
• consists of ribose, adenine and 3 phosphate groups

Question 3

What is the purpose of ATP hydrolysis.

Answer 3

it provides immediate energy to processes

active transportor and muscle contraction for example

Question 4

Describe the process of ATP hydrolase.

Answer 4

• there is small activation energy required to break covalent bond holding last ATP molecule
• this bond is broken by the enzyme ATPase or ATP hydrolase and a large amount of energy is released
• it produces ADP and a phophate molecule

Question 4

What is the eqution for ATP hydrolase?

Answer 4

ATP + H2O → ADP + Pi + energy

the i in Pi says that the phosphate molecule is inorganic

Question 5

What happens after ATP hydrolase?

Answer 5

• ADP and phosphate is released recycled back into ATP trhough condensation
• it is catalysed by ATP synthase
• and is an example of a phosphorylation reaction

it occurs in respiration and photosynthesis

Question 6

What enzyme catalyses ATP hydolysis?

Answer 6

ATPase / ATP hydrolase

Question 7

What catalyses the condensation of ADP and phosphate?

Answer 7

ATP synthase

Question 8

What is a phosphorylation reaction?

Answer 8

a reaction where phosphate is added to a molecule

Question 9

What can the phosphate molecule produced at the end of ATP hydrolase be used for?

Answer 9

it makes compounds more reactive by phosphorylating them

this will speed up reactions

Question 10

What are the properties of ATP?

Answer 10

• immediate source of a manageable amount of energy
• ATP is stored in small quantities so it can quickly be reformed from ADP
• can be used in a multitude of processes
