Presentation Transcript

  1. Chemical Energy and ATP

  2. Energy and ATP • Energy in glucose & lipids is converted into ATP • Adenosine triphosphate • Energy for work is stored in ATP bonds • Energy released when 3rd phosphate is broken off • 3rd bond unstable…easily broken • ADP left over • ATP recreated with the addition of another phosphate group

  3. Digestion • Purpose: Break food into useable molecules to create ATP • Higher calorie foods will produce more ATP molecules • 1 glucose = 36 ATP (carbs = preferred source) • Proteins less likely to be broken into ATP • Amino acids are needed for other processes

  4. Energy on Earth • Most life relies on sunlight directly or indirectly • Directly: Plants • Indirectly: Animals • Exceptions: Chemotrophs • Hydrothermal vents release chemicals called sulfides • Sulfides are the energy source used to make ATP (chemosynthesis)
