Adenosine triphosphate

Question 2

What is ATP synthesised from?

Answer 2

ADP and inorganic phosphate (Pi)

Catalysed by ATP synthase

Question 3

What is ATP broken down in?

Answer 3

ATP –> ADP + Pi

Catalysed by ATPase

Question 4

Define coupled reaction

Answer 4

Breakdown of ATP same time as another reaction using energy

Question 5

Why is ATP a good source of energy?

Answer 5

• ATP stored/released in small amounts - no energy wasted!
• Single step process - immediate energy release!
• Small soluble - easily transported and used up
• Transfer energy to another molecule by transferring one of phosphate groups
