ATP

Question 1

what is ATP?

Answer 1

adenosine triphosphate

Question 2

what is the role of ATP?

Answer 2

supply energy for synthesis, transport and movement in cells

Question 3

describe the structure of ATP

Answer 3

• 3 phosphates (circles)
• ribose sugar (pentagon)
• adenine (pentagon and hexagon)

Question 4

what is the equation for the breakdown of ATP into energy?

Answer 4

ATP + H2O –> ADP + Pi + energy

Question 5

what type of reaction is the breakdown of ATP?

Answer 5

hydrolysis

Question 6

what is the equation for the formation of ATP

Answer 6

ADP + Pi –> ATP + H2O

Question 7

what type of reaction is the formation of ATP?

Answer 7

condensation
- uses enzyme ATP synthase

Question 8

what is ADP?

Answer 8

adenosine diphosphate

Question 9

describe the properties of ATP

Answer 9

• small, moves in and out of cells easily
• water soluble, energy-requiring processes happen in aqueous environments
• energy released in small quantities, so energy isn’t wasted as heat
• easily regenerated, can be recharged with energy
• unstable phosphate bonds, not long term energy store
