Energy Transformations: 1. Cellular respiration (Figure 9.2): All organisms do cellular respiration - Breakdown glucose release energy then capture the energy in ATP o ADP + P + energy ATP (7.3 kcal/mole) endergonic reaction o Glucose + Oxygen CO 2 + H 2 O + energy (-686 kcal/mole) exergonic reaction 2. Photosynthesis *Both of these must occur in the cell; laws of thermodynamics Where and how is most of the ATP produced in your cells? Where: In the mitochondrion, ATP synthase (enzyme that synthesized ATP) How: Chemiosmosis or Oxidative Phosphorylation (Figure 6.17) Where does the energy required for ATP synthesis come from? Proton of hydrogen ion gradient Where does Hydrogen ion gradient come from? Active transport of hydrogen ions powered by the flow of electrons along the ETC (Electron transport chain); Involved redox reactions IMPORTANT REACTIONS AND MOLECULES: Redox Reactions: Figure 9.15 reduction : Addition of electrons or hydrogen to a molecule that adds energy (stores energy in reduced compounds)
