Bioenergetics #FINAL 2

• Bioenergetics


  The study of energy in living systems (environments) and the organisms (plants and animals) that utilize them
• Energy


  Required by all organisms May be Kinetic or Potential energy
• Kinetic Energy


  Energy of Motion Heat and light energy are examples
• Potential Energy


  Energy of position Includes energy stored in chemical bonds
• Two Types of Energy Reactions

  Endergonic Reactions Exergonic Reactions
• Endergonic Reactions


  Chemical reaction that requires a net input of energy
• Exergonic Reactions


  Chemical reactions that releases energy Cellular Respiration
• Metabolism


  The sum total of the chemical activities of all cells.
• Two Types of Metabolism

  Anabolic Pathways Catabolic Pathways
• Anabolic Pathway


  Metabolic reactions, which (consume energy) (endergonic), to build complicated molecules from simpler compounds.
• Catabolic Pathway


  Metabolic reactions which (release energy) (exergonic) by breaking down complex molecules in simpler compounds
• ATP Components

  adenine, ribose, 3 phosphate groups
• Adenosine Triphosphate


  ATP
