adenosine triphosphate

Question 1

Name three biological processes that require ATP

Answer 1

Active transport
Muscle contraction
Cell division

Question 2

Name the biological molecule category that ATP fits into

Answer 2

Nucleic acids

Question 3

Name the three parts of ATP

Answer 3

3 phosphates
Ribosome
Adenine

Question 4

Write the full name for ATP

Answer 4

Adenosine triphosphate

Question 5

How many phosphates does one molecule of ATP have?

Answer 5

3 phosphates

Question 6

Is it hydrolysis or condensation that breaks off the terminal phosphate in an ATP molecule?

Answer 6

Hydrolysis
A bond is broken and energy is released via the enzyme ATP hydrolase
(And the addition of water)

Question 7

When the bond is broken between the terminal phosphate, what molecule does ATP become?

Answer 7

ADP

Question 8

What does Pi stand for?

Answer 8

Inorganic phosphate

Question 9

What is phosphorylation?

Answer 9

Addition of a phosphate molecule

Question 10

Does phosphorylation make molecules more or less reactive?

Answer 10

More reactive

Question 11

What is the type of bonds formed between the adenine and ribose in a molecule of ATP?

Answer 11

Glycosidic bonds

Question 12

What is the type of bonds formed between the first phsophate and ribose in a molecule of ATP?

Answer 12

Phosphodiester bonds

Question 13

What is the type of bonds formed between the end two phosphates in a molecule of ATP?

Answer 13

Weak phosphanhydride bonds

Question 14

Describe what happens during the condensation of ATP

Answer 14

• a bond is formed and energy is stored via the enzyme ATP synthase
• One inorganic molecule is added
• ATP and water is produced

Question 15

Describe what happens during the hydrolysis of ATP

Answer 15

• ATP is constantly hydrolysed then made again via a condensation reaction
• weak phosphanhydride bonds between the end two phosphates break
• reaction is catalysed visa the enzyme ATP hydrolase
• ADP and Pi are formed
