Figure 24.4a High-energy phosphate groups are transferred directly from phosphorylated substrates to ADP ATP is synthesized via substrate-level phosphorylation in glycolysis and the Krebs cycle

Figure 24.4a OUTLINE ENERGY—WHERE DO YOU GET IT?; HOW IS IT USED?; WHAT BIOLOGICAL SYSTEMS USE IT? 1) TALK ABOUT ENERGY 2) STUDY CHARACTERISTICS OF ATP/ADP 3) OVERVIEW OF GLYCOLYSIS, KREBS CYCLE AND RESPIRATORY CHAIN / ELECTRON TRANSPORT. 4) GLYCOLYSIS WHAT DOES THIS WORD MEAN? ENERGY RELEASED / USED? HOW IS ENERGY CAPTURED?; ENERGY MADE? WHAT FORM?; CHEMICAL PRODUCTS?
Energy

Energy

The capacity to do work (put matter into motion) Types of energy Kinetic – energy in action Potential – energy of position; stored (inactive) energy (eg. glycogen)
Chemical Senses
