Pre AP - CELL ENERGY NOTES
I. Energy
A. Energy for living things comes from Originally the energy in food comes from B. Uses light energy from the sun to produce food –
Examples:
C. Cannot use the sun’s energy to make food –
Examples:
II. Cell Energy
A. Cells usable source of energy –
1. ATP stands for adenosine triphosphate
2. ADP stands for --
ATP
B. All energy is stored in the bonds of the compound
Breaking the bond releases energy
C. When cell has energy available it can store this energy by adding a phosphate group to ADP, producing
ATP
D. Example:
