Q4: Generation of ATP

Question 1

ATP molecule is

Answer 1

a phosphorylated macromolecule

Question 2

Three components of ATP

Answer 2

Adenine
Ribose
Phosphates

Question 3

Adenine

Answer 3

a nitrogen containing organic base

Question 4

Ribose

Answer 4

A sugar molecule with a five carbon ring structure (pentose sugar) that acts as the backbone to which the other parts are attached.

Question 5

Phosphates

Answer 5

a chain of three phosphate groups

Question 6

ATP is a

Answer 6

nucleotide

Question 7

How is energy stored in ATP

Answer 7

In the bonds between the phosphate groups which are unstable so have a low Ea so are easily broken. Release a considerable amount of energy when they do break.

Question 8

Equation for hydrolysis of ATP

Answer 8

ATP + (H2O) > ADP + Pi + energy

Question 9

Hydrolysis of ATP enzyme

Answer 9

ATP hydrolase

Question 10

Formation of ATP enzyme

Answer 10

ATP synthase

Question 11

Formation of ATP is what type of reaction

Answer 11

condensation reaction

Question 12

Addition of a phosphate molecule to ADP occurs in 3 ways

Answer 12

• photophosphorylation
• oxidative phosphorylation
• substrate-level phosphorylation

Question 13

ATP

type of energy source

Answer 13

immediate

Question 14

Energy released by ATP in comparison to glucose

Answer 14

• each ATP molecules releases less energy compared to glucose
• smaller, more manageable quantities
• hydrolysis of ATP is a single
• breakdown of glucose is lots of reactions

Question 15

ATP cannot be stored so

Answer 15

continuously made in mitochondria within cells that need it

Question 16

ATP used in energy-requiring processes

5

Answer 16

• metabolic processes
• movement
• active transport
• secretion
• activation of molecules
