1
Photosynthesis and Respiration Energy Transformation Within Cells
2
Energy Transactions
3
ATP and energy storage
4
ATP provides energy for coupled reactions
5
Electron carriers (like NAD) provide reducing (bond-making) power (a high energy electron to share in a bond) for coupled reactions
6
Photosynthesis
7
An overview of photosynthesis The H is sharing a high energy electron that will be used to make a bond. The electron was captured and energized in the light reactions. The electron will be used to glue the carbons together from CO 2 to make new carbon chains: sugar.
