BIO 101 Notes 3116 ● It takes more energy to break what bond than the others? Covalent Bond ● Where would you find covalent bonds in car Energy conversion slide? Gasoline for car and food for the cell ● What sugar makes up starch? G lucose ● How many carbon atoms does glucose have? 6 held together by covalent bond ● What is the universal form of energy in any biological system?ATP ● You are using energy at all times Aerobic Respirations Summary Oxidation(Glucose Loses electrons and hydrogen C6H12O6 + O26CO2 + 6H2O Oxygen and water are reduced, Oxygen gains electrons and hydrogen ● The starting materials for photosynthesis are carbon dioxide and water, takes place in the chloroplast in a green plant. ● In the membrane area you find the process of photosynthesis pigments; in the protein area ● We want to get as much ATP out of the glucose molecule ● We need the right amount of Oxygen at all times to produce ATP Biological Oxidation; Cell Respiration ● Energy releases Rx ● Releases energy stored in glucose ● What is the difference between starch and cellulose; they are both made of glucose although they have different make ups ● Metabolic Rxenzyme controlled release of energy ● Enzymes are very specific for a particular chemical reaction based on the substance and what they are reacting to. ● Total energy released with complete oxidation of glucose686,000 Calories/mole ● Energy in form of; ATP and Body heat Types of Respiration ● Aerobicrequires use of Oxygen to completely release energy in glucose ● Anaerobictakes place in absence of oxygen ○ results in an incomplete oxidation of glucose energy ○ They do not have mitochondria; like bacteria and some yeast ● Where does the alcohol in wine and beer come from? Fermentation of that energy source from grains, they are not broken down all the way so the endpoint for their process is producing alcohol ● Aerobic respiration users require oxygen for circulatory system and respiratory system when being active, the glucose in your cells isn’t completely broken down due to lack of oxygen lactic acid is produced. ● Lactic acid build up causes your muscles to feel sore and burn and cramp or spasm ● Aerobically working outrunning, swimming, cardio ● Trying to build muscle you lift weights until you get the burn which is the lactic acid 4.1 Opening Questions; Hungry? ● What does burning calories really mean? ● Why do we get hungry? ● Why do we need to breathe? 4.7 Aerobic Respiration ● aerobic respiration requires oxygen ● it takes place inside the mitochondria ● aerobic respirations happens in both producers and consumers ● What is the first stage of aerobic respiration called? Glycolysisthe main goal is to take the glucose molecule and break it in half ● The next two stages take place in the mitochondria pyruvic acid and is broken down in the krebs cycle; both glycolysis and krebs cycle have low ATP; instead they change the molecular structure of the glucose that they started with. ● The third stage is in molecular structure of mitochondrialcytochromes are linked together and have the ability to accept and donate electrons or hydrogens and within that sequence of electron or hydrogen transfer; they move from a high level of potential energy to low level of potential energy ○ there are three places where there is a sufficient drop due to highlow potential energy transfer which produces ATP ● For every electron and hydrogen we will get 3 units of ATPwhen they get to the end of the line they need something to accept the ATP molecule ● IF there is not oxygen at the end of the sequence to accept the hydrogen they get all bottled up ● If there is oxygen and hydrogen then it makes water which is needed ● Lactic acid buildup in muscle tissue which is not good
