*Essential Study Material!!
*For you, at a price that's fair enough!!
Oxidation reduction reactions involve the gain or loss of electrons or H+ ions
O. I. L. R. I. G
Oxidized is Less, Reduced is Gain Oxidation is to lose, reduction is to gain
The shift of an electron from one compound to another removes some potential energy from the
first compound (oxidized compound) and increases the potential energy of the second
compound (reduced compound)
Photosynthesis is a redox reaction
Electron Carriers:
Coenzymes NAD+ and FAD shuttle electrons. High energy electron carriers recycled
Photosynthetic Organisms
Autotrophs produce their own carbs through photosynthesis
Heterotrophs gain their energy from consuming other organisms
Materials flow between heterotrophs and autotrophs
Photosynthesis takes place in the chloroplast
Photosynthesis includes light reactions from the Calvin Cycle
Solar Energy to Chemical Energy
