Day 3. TCA cycle and Oxidative Phosphorylation

• in mitochondria
• AcetylCoA (acetyl group) is completely oxidized to CO2.
• energy saved as NAHD, FADH2 and GTP
• no hormonal control as energy need doesn't depend on fed-state
• control mechanism - energy status of the cell
• enzymes in the matrix of the mitochondria, except succinate dehydrogenase (inner membrane)
• electron transport chain creates H+ gradient between two sides of the enner membrane of the mitichondra
• the H+ gradient's energy is used for making ATP
