1. ATP
Energy for the cell

2. Bell Ringer
Grandmother Mary decides to give you $50 for Christmas. Would you like to have a fifty dollar bill or broken into different bills?
Explain your answer
Discuss the advantages and disadvantages

3. Where is the energy coming from
How do the following obtain food:
Plants
Humans
Heterotrophs
Autotrophs

4. Does food give you direct energy
Food must be broken down in several processes to make ATP.
Food has potential energy, stored as suger and carbon based molecules
ATP is used directly by the cell
ATP is made up of adenosine, ribose and three phosphates
How does ATP produce energy?

5. ATP the energy carrier
Break a phosphate bond to release energy (exothermic)
Become ADP ADP + > ATP ATP> ADP +P
Cycle back endothermic to get back to ATP
Glycolysis produces 4 ATP, net gain of 2 because of 2 needed to start glycolysis
Cell Respiration is 38ATP, net gain of 36, 2 start as well.
