Energy and ATP Energy in glucose & lipids is converted into ATP Energy in glucose & lipids is converted into ATP Adenosine triphosphate Adenosine triphosphate Energy for work is stored in ATP bonds Energy for work is stored in ATP bonds Energy released when 3 rd phosphate is broken off Energy released when 3 rd phosphate is broken off 3 rd bond unstableeasily broken 3 rd bond unstableeasily broken ADP left over ADP left over PPP ENERGY ADENOSINE TRIPHOSPHATE ADENOSINE DIPHOSPHATE

Transcript

  • Chemical Energy and ATP

  • Chemical Energy and ATPLife depends on energyThat energy is stored in chemical bonds of energy storing compoundsATP, NADH, NADPH and FADH2The chief energy storing compound = ATPAdenosine triphosphateEnergy for work is stored in ATP bonds3 parts: ribose (sugar), adenine and a 3 phosphate chain

  • Energy and ATP3 Main types of biological work1. Energy for the mechanical functions of the cells 2. Movement, transport of materials, etc.3. synthesis and breakdown of large cells

  • ATPATPATPATPDigestionPurpose: Break food into useable molecules to create ATPHigh calorie foods will produce more ATP moleculesUsually carbohydrates and lipidsProteins (amino acids) are usually needed elsewhere

  • Energy on EarthMost life relies on sunlight directly or indirectlyDirectly: PlantsIndirectly: AnimalsAutotrophsOrganisms that make food from CO2 and an energy source (such as the sun)Known as producersNRG for now and later

  • Energy on EarthMost life relies on sunlight directly or indirectlyDirectly: PlantsIndirectly: AnimalsHeterotrophsOrganisms that cannot make their own foodKnown as consumersObtain that energy either directly or indirectly

  • Energy on EarthMost life relies on sunlight directly or indirectlyDirectly: PlantsIndirectly: AnimalsExceptions: ChemotrophsHydrothermal vents release chemicals called sulfidesUnique bacteria feed on the sulfides to make ATP (chemosynthesis)

  • ReviewWhere is the energy of ATP stored? How is ADP and ATP different? Whats the purpose of digestion?Why are proteins less likely to be broken into ATP?How is chemosynthesis and photosynthesis similar? Different?

  • ReviewWhere is the energy of ATP stored? In its bondsHow is ADP and ATP different? ADP has one less phosphate molecule than ATP. ATP is a higher energy molecule.Whats the purpose of digestion?Break food into useable molecules to create ATPWhy are proteins less likely to be broken into ATP?Amino acids are needed for other processes

    How is chemosynthesis and photosynthesis similar? Different?Similar: Both are processes that capture energy and store it as sugarsDifferent: Chemosynthesis captures chemicals to make sugarsDifferent: Photosynthesis captures sunlight to make sugars
