Bio 110 Week 3 Notes Chapter 3 Energy and Life Is energy the secret of life 0 Two main points you must know 1 Life acquires energy from its surroundings 2 The Earth has been changed because of life s need for energy Introduction 0 The origin of life and proton gradients Low pH Acidic 4 4 High pH Alkaline 0 Life evolves and adapts and changed the Earth 0 Life needs energy 31 Energy 0 What is Energy 0 A property of objects that can be transferred or transformed 0 Subject to the laws of thermodynamics 0 Important Scientists 0 Albert Einstein I Contribution Emc2 Measures Energy I If you can t eXplain it simply you don t understand it well enough 0 Mass energy equivalence Energy obeys the laws of thermodynamics 0 Energy transformations 0 Work Kinetic Energy 0 Random motion of air 0 Light waves electromagnetic energy Potential Energy 0 Chemical Energy coal power 0 Nuclear power 0 Water behind a damn 0 Concentration gradients which is very important to all living things on this planet 32 Chemical Reactions and Energy Autotrophs 0 Is self feeding take energy from the sun and stores it Heterotrophs 0 Need to get their energy for eating others to obtain the energy within Exergonic Reactions 0 Glucose Oxygen Carbon Dioxide Water Energy C6Hl206 602 Reactions Endergonic Reactions 0 Glucose Oxygen 6CO2 6H2O Energy Reactions ATP The energy currency of life 6CO2 6H2O Energy heat Products 94 Carbon Dioxide Water Energy C6Hl206 602 Products Cells evolved the ability to utilize proton gradients to make ATP 0 Chemiosmosis Endergonic Reaction means to push 0 ATP Synthase I Repurposing electron transport and ATP synthase 33 Photosynthesis Changed the World Cyanobacteria Autotrophs 0 Before plants bacteria created Photosynthesis 0 Sun emits Electromagnetic Energy 0 Fun Facts 0 The reason why plants are green is because the plant is re ecting green light off itself and to our eyes All carbon in your body has Photosynthesis Oxygen is a oxidized iron in the oceans Created banded iron formations Source of steel for industry Valyrian Steel I Molten iron can also destroy terminators GOOD 0 Photosynthesis takes two parts 1 Light Reaction a Energy in sunlight is transformed to chemical potential energy Water H20 is split into hydrogen and oxygen Electrons are energized by the sunlight to power giant proton pumps The light reaction generates a proton gradient Proton gradients are used to regenerate ATP i Chemiosmosis Endergonic Reaction 2 Synthesis Calvin Cycle 0990 34 Aerobic respiration an evolutionary consequence of oxygen Aerobic respiration utilizes oxygen and makes it less harmful by forming water Evolution of aerobically respiring bacteria Aerobic respiration occurs in three main stages 1 Glycolysis 2 Krebs Cycle 3 Oxidative phosphorylation electron transport and chemiosmosis The Electron Transport Chain and Oxidative Phosphorylation 0 The importance of oxygen in Oxidative Phosphorylation 35 How life changed the world 0 Importance of oxidative phosphorylation for ATP production 0 Endosymbiosis O A key evolutionary event that led to Eukaryotes O Eukaryotic cells were a major cellular restructuring O Eukaryotic cells formed multicellular organisms 0 Aerobic respiration led to an active life style of animals 0 How life changed the world by using oxygen is used to create the ozone layer End of Week 3 notes 0 Important There will be a test next Friday 911 and hopefully I will be able to finish the study guide by Tuesday or Wednesday at the latest 0 Also Week 4 Notes will hopefully be upload by next Wednesday or Thursday at the latest Thank you for using Studysoup and have a great three day weekend
