3.11 ATP

Question 1

What do cells require energy for

Answer 1

Synthesis
Transport
Movement

Question 2

What does atp stand for

Answer 2

Adenosine triphsophate

Question 3

What is atp made of

Answer 3

Nitrogenous base - adenine
Pentose sugar - ribose
3 phosphate groups

Question 4

How does atp release energy

Answer 4

When the phosphate group is removed from the molecule a large amount of energy is released when the phosphate undergoes other reactions involving bond formation

Question 5

How much energy is released than used in the soliciting of atp to create energy

Answer 5

30.6KJ mol-1

Question 6

What reaction is used to remove the phosphate group from atp

Answer 6

Hydrolysis reaction

Atp + water > adp + pi + energy

Question 7

What is phosphorylation

Answer 7

Reattaching a phosphate group to adp molecule

Removing a water in the process so it’s a condensation reaction

Question 8

Why is atp a good immediate energy store

Answer 8

Inter conversion of atp and adp is constantly happening in all living cells

Question 9

What are the properties of atp

Answer 9

Small
Water soluble
Released energy in small quantities
Easily regenerated
