World energy supplies are often measured in the unit of quadrillion British thermal units (1012 Btu), generally called a “quad.” In 2015, world energy consumption is projected to be 5.81 × 1017 kJ.
(a) With reference to Exercise 5.17, how many quads of energy does this quantity represent? (b) Current annual energy consumption in the United States is 99.5 quads. Assume that all this energy is to be generated by burning CH4(g) in the form of natural gas. If the combustion of the CH4(g) were complete and 100% efficient, how many moles of CH4(g) would need to be combusted to provide the U.S. energy demand? (c) How many kilograms of CO2(g) would be generated in the combustion in part (b)? (d) Compare your answer to part (c) with information given in Exercise 5.111. Do you think that photosynthesis is an adequate means to maintain a stable level of CO2 in the atmosphere?
Cellular Respiration Notes The last bond on ATP is very high energy, and when this breaks off this energy is used Condensation reaction- Reattach the Phosphate to ADP to make it ATP again Glucose can be broken to produce ATP 1) Glycolysis- Make glucose into Pyruvate which produces 2 ATP molecules After this 2 Pyruvates are converted into Acetyl CoA, these will go through the Kreb Cycle 2) Kreb Cycle- Acetyl CoA goes through and NADH and FADH2 are produced along with CO2 NADH and FADH2 assist the mitochondria in creating a proton gradient, inside inner membrane of mitochondria, this will help with ATP Synthase, this takes an ADP and Phosphate group and combines them to create ATP 3
