Question 1

What are the uses of ATP

Answer 1

• active transport
• muscle contraction
• protein synthesis

Question 2

structure of ATP

Answer 2

• nitrogenous base (adenine)
• Pentose sugar (ribose)
• 3 phosphate groups

Question 3

ATP synthase

Answer 3

Enzyme that catalyses production of ATP

Question 4

ATP synthase found in human cells.
Suggest why human ATP synthase is not inhibited and bacterial synthase
is inhibited.

Answer 4

Human ATP synthase has a different tertiary structure to
bacterial ATP synthase

Question 5

Describe how ATP is resynthesised in cells.

Answer 5

From ADP and phosphate;
2. By ATP synthase
