Question 1

Why are fats preferred as energy storage

Answer 1

-because fats are much more energy-dense than other biomolecules

Question 2

What are the two ways ATP can form

Answer 2

• it can form through substrate-level phosphorylation

- it can form through oxidative phosphorylation

Question 3

How is ATP consumed

Answer 3

-through hydrolysis or transfer of phosphate group to another molecule

Question 4

What makes ATP a high energy compound

Answer 4

• because of the repulsion of the negative charges on the phosphate groups
• > after hydrolysis, note that ATP is much more stable

Question 5

What is meant by ATP cleavage

Answer 5

• it is the transfer of a high energy phosphate group from ATP to another group
• > the overall free energy of the reaction is determined by taking the sum of the free energies of the individual reactions
