Document Summary
En e rgy, enzy m es, an d metabol is m. What physical principles govern biological energy t ransformations? energy transformations: Are linked to chemical transformations in cells. Bio final exam notes that act as control mechanisms. Metabolism exhibits 2 types of reactions: anabolic reaction (e. g photosynthesis) Simple molecules linked together to form complex molecule. Energy is required and stored in chemical bonds: catabolic reaction. Complex molecule are broken down into simpler molecules. Metabolism transforms matter and energy: energy = the capacity to do work or the capacity to change, kinetic energy = energy of motion; includes energy that does work, potential energy = energy of state or position www. notesolution. com. Includes energy stored in- chemical bonds: concentration gradient, charge imbalance, potential energy can be converted to kinetic energy. Changes in free energy change tells reaction type changes in free energy (g), total energy or enthalpy (h), temperature (t), and entropy (s) are related by the equation:
