Oxidative phosphorylation occurs in aerobic cells to generate energy through metabolism. Photophosphorylation is the process of capturing solar energy and converts to chemical energy. 

Topics covered include: ATP Synthesis, Regulation of Oxidative Phosphorylation, Mitochondrial Genes, The Role of Mitochondria in Apoptosis and Oxidative Stress, General Features of Photophosphorylation, Light-Driven Electron Flow, & ATP Synthesis by Photophosphorylation.
