Energy

What is Energy? DEF: ability to do work or cause change

Adenosine TRIphosphate How Do We Make Energy? Energy, from food, is converted into a compound called ATP: Adenosine TRIphosphate This conversion occurs in the cells of your body

ATP

ATP = Fully Charged Battery ATP = ENERGY CARRIER Energy needs vary so it is stored in ATP ATP gives us full energy when we need it ATP = Fully Charged Battery Like a battery provides 100% energy to a flashlight, ATP provides 100% energy to our bodies!!!! + -

ADP = Partially Charged Battery When one compound of ATP releases energy, ATP is changed into ADP: Adenosine DIphosphate What does the DI mean? ______ Where is the energy going? Energy is released when the bond between the 2nd and 3rd phosphate of ATP is broken. 2 ADP = Partially Charged Battery

ADP = Partially Charged Battery ADP: missing 1 phosphate element Happens as a result of energy usage Like a battery that needs to be recharged when at 50% ADP provides only 50% of energy -

It needs to be RECHARGED!!! When you eat again, energy is provided to add P element to form ATP Happens as a results of consuming energy

It’s a CIRCLE!!!! Like a re-chargable battery can be re-charged ADP can be re-charged to ATP ATP remains in this form until energy is needed again When energy is needed again, ATP is converted into ADP The circle never ends!!!!!

Energy Released Energy Consumed ATP ADP Like a 50% battery is re-charged to 100% ADP is re-charged ATP when energy is used When energy is consumed, ADP converted ATP

Additional Questions When do we release energy? When do we consume energy?
