4. Draw a free energy reaction coordinate diagram for both a generic endergonic and a generic exergonic reaction (label each). Make sure to label the x- and y-axes. Now label where reactants and products should go on the figure. Draw something that illustrates the free energy change for each reaction. Now write something like the following next to your figures: “reactants <—> products”. a. What do the reaction coordinate diagrams have to do with the text you just wrote? b. What...
How does ATP-ADP couple (link) endergonic and exergonic reactions?
Exergonic and Endergonic Reactions What would happen if you rapidly shake a bottle of sand? How does this demonstrate the first law of thermodynamics? Free energy Energy released to surroundings Reactants (marble at top) Products (marble at bottom of hill)
Consider a catabolic chemical reaction Please explain the answer - How do the energy levels of the reactants and products compare? - is this reaction exergonic or endergonic? - Energetically, how might an enzyme catalyze this reaction?
1. What are the different sources of energy available to living organisms? 2. How do the acquisition and the use of energy by living organisms work according to the laws of thermodynamics? 3. Explain the energy use in the following reactions: endergonic/exergonic. 4. What is metabolism? How are chemical reactions related to metabolism? Why is energy needed to run a metabolism? What are coupled reactions? 5. Draw a picture of ATP. Why is this molecule so important for cells? How...

Requirements for each to work.) 2) Why is SN2 is in direct competition with E2 while SN1 is direct competition with E1 reaction. 3) Rate expression of each 4) which reactions are concerted? Which are atep wise? 5) which are sterospecific and what stereospecificity of each are? 6) how do the variables below (A-D) influence reaction pathway? Compare and contrast SNI, SN2, El and E2 reactions. What...
Compare and contrast the circumstances faced by people with disabilities in the US and in Australia. 1. How does socioeconomic status or the overall economy of the country affect disabled communities? 2. Do people living with disabilities in these countries have equal access compared to their non-disabled counterparts?
