a major concern for perspective. Electric car owners is called range anxiety. How far can you go in a single charge? Surveys show that Americans want to go hundreds of miles, even though the average daily auto uses only around 40. But there is some justification for most of the country. Roadside charging stations are few and far between. Despite lackluster sales, electric carmakers continue to test the waters with lower prices. And longer range is like the Chevy Bolt, the first moderately priced all electric car with a range of more than 200 miles, or the new Tesla Model three, which has a similar price and range. Anticipating a large demand, Tesla plans to produce 500,000 cars a year in the latter half of the decade. What is the path that electrons take on the way from glucose to oxygen? First stop is a positively charged electron except ER called nicotine a meid, adenine di nucleotide, or N a D. Positive for short that sells make from niacin, a B vitamin. A transfer of electrons from organic fuel to N A B positive reduces it to N. A. T. H. Three h represents the transfer of hydrogen along with the electrons. Using the analogy of a staircase, the electrons have now taken a small step down in the trip from glucose to oxygen. Rest of the staircase consists of an electron transport chain in a series of oxidation reduction reactions called redox reactions for short. Each member of the chain first accepts and then donates electrons with each transfer. The electrons give up a small amount of energy that can be used in directly to generate a dentist scene. Triphosphate or a teepee. The first molecule of the chain accepts electrons from glucose and other fuel molecules and deposits them at the top of an electron transport chain. The electrons cascade down the chain from molecule to molecule, like an electron bucket. Brigade molecule at the bottom of the chain finally drops the electrons toe oxygen. At the same time, oxygen picks up hydrogen forming water. The overall effect of this transfer of electrons during cellular respiration is a downward trip for those electrons, from glucose to N A. T H to an electron transfer chain to oxygen during the stepwise release of chemical energy during electron transport ourselves make most of their A T P it is actually oxygen, the electron grabber that makes it all possible by pulling electrons down the transport chain from fuel molecules, oxygen functions like gravity pulling objects downhill. This is how the oxygen we breathe functions in ourselves and why we cannot survive more than a few minutes without it.
