ATP and energy transfer

Question 1

ATP and energy transfer (definition)

(3 types of energy)

Answer 1

Is the capacity to perform work and can exist in chemical, potential and kinetic forms

Chemical energy

• Comes from the food we eat

Potential energy

• Stored in the body/tissues

Kinetic (movement) energy

• When we contract our muscles

Question 2

Food we eat is stored as: (3 things)
(all of which…)
(when …)

Answer 2

• Amino acids
• Triglycerides
• Glycogen

All of which are ready to be used as fuel for energy production.
When metabolised they are converted in the compound of ATP

Question 3

ATP is made up of

Answer 3

one molecule of adenosine and three phosphate molecules held together by high energy bonds

Question 4

To extract the energy from ATP, an enzyme…

Answer 4

ATPase is released this stimulates the final high energy bond to be broken

Question 5

This release of energy is known as an

Answer 5

exothermic reaction

Question 6

This causes the release of energy for muscular contraction and leaves

Answer 6

adenosine diphosphate (ADP) and a single phosphate (P)
