3.1.6- ATP

Question 1

ATP

Answer 1

adenosine triphosphate

Question 2

What is ATP made of?

Answer 2

adenine, ribose, 3 phosphate groups

Question 3

What is ATP broken down into?

Answer 3

ADP and phosphate

Question 4

What enzyme is used in hydrolysis of ATP?

Answer 4

ATP hydrolase

Question 5

Why does hydrolysis of ATP release so much energy?

Answer 5

Bonds between each phosphate group are unstable and are easily broken

Low activation energy means energy is released quickly

Question 6

Hydrolysis of ATP

Answer 6

ADP + Pi + energy

Question 7

Weaknesses of ATP availability

Answer 7

Weak phosphate bonds means it’s not a long term energy store and can’t be stored in large quantities

Question 8

Strengths of ATP availability

Answer 8

Energy is released in smaller, more manageable chunks

Breakdown is a single reaction so energy is released quicker

Question 9

Stage 1 of ATP synthesis

Answer 9

ATP is broken down by hydrolysis into a phosphate and adp

Question 10

Stage 2 of ATP synthesis

Answer 10

Energy is released

Question 11

Stage 3 of ATP synthesis

Answer 11

ADP, ATP synthase and a phosphate are required and they are joined together in a condensation reaction

Question 12

ADP

Answer 12

adenosine diphosphate
