The second law of thermodynamics tells us that life evolved in a universe that tends towards disorder. Gases expand to fill the space enclosing them, dissolved molecules spread throughout the solvent containing them, and large molecules fall apart to become smaller ones. Despite this, we know that cells can make large molecules and break them down. Because of the first law of thermodynamics, (energy can't be created or destroyed, but it can be converted between forms) cells can carry out anabolism and catabolism. For example, they can make and breakdown fatty acids. In this question you will consider the strategies cells and enzymes used to perform these processes in the context of biosynthesis and oxidation of fatty acids.
Compare and contrast fatty acid biosynthesis and -oxidation.
Many microorganisms in lakes use cellular respiration to generate energy. Dumping large amounts of raw sewage into rivers or lakes typically leads to massive fish kills, even if thesewage itself is not toxic to fish. What kills the fish? How might you reduce fish mortality after raw sewage is accidentally released into a small pond?

- Figure 4.5 Energy inputs and outputs in chemical reactions. 1 Some reactions convert molecules with lower energy to molecules with higher energy, so they require a net energy input in order to proceed. 2 Other reactions convert molecules with higher energy to molecules with lower energy, so they end with an energy release Figure It Out: Which law of thermodynamics explains energy inputs and outputs in chemical reactions?arrow_forwardIf a compound that allows protons to freely diffuse across membranes is added to cells that are actively metabolizing glucose via cellular respiration, which of the following processes would stop? Glycolysis Electron transport ATP synthesis None of the above All of the abovearrow_forwardThe movement of energy between living organisms is a matter of atoms, molecules and compounds being built into larger molecules or being broke into smaller ones. Reviewing the two equations for energy transference, which one is building energy? 6CO2 + 6H2O + energy --------> C6H12O6 + 6O2 C6H12O6 + 6O2 ---------> 6CO2 + 6H2O + energyarrow_forward
- During aerobic respiration in the mitochondria of eukaryotes, which product molecules contain the oxygen atoms that started out in substrate diatomic oxygen gas molecules? cell biology carbon dioxide only C6H12O6 only glucose only CO2 only H2O onlyarrow_forwardUse this analogy "A baker starts with a bowl of dough and eventually turns it into all sorts of goodies" to explain the events of the Krebs Cycle and the Electron Transport Chain.arrow_forwardMany plastic materials are organic polymers that contain carbon and hydrogen. The oxidation of these plastics in air to form carbon dioxide and water is a spontaneous process; however, plastic materials tend to persist in the environment. Explain.arrow_forward
- Which of the following statements describes the end step for the electron transport chain? A. H+ ions flow down the gradient to generate ATP B. electrons are transferred to NADH and FADH2 for chemiosmosis C. electrons are transferred to oxygen, causing it to split and take up H+ ions, which form water D. H+ are pumped across the inner membrane of mitochondria to establish an electrochemical gradientarrow_forwardWhich statement best describes an electron transfer chain? It generates energy from carbohydrates. It is used by cells to dispose of excess electrons. It utilizes ATP to synthesize nutrients. It transfers energy, stepwise, from one compound to another. It requires activation by oxygen.arrow_forwardEnergy is required to reverse the flow of the electron transport chain. Why would this be so?arrow_forward
