Question
2. (2) Molecules called uncouplers (such as dinitrophenol) poke holes in the inner mitochondrial membrane. What effect would this have on aerobic respiration? From The Joy of Fermentation Video 3. (2) Define "exogenous" and "endogenous" electron acceptors. 4. (4) The conversion of pyruvate to lactate in lactic acid fermentation and the conversion of pyruvate to ethanol in alcoholic fermentation does not produce ATP- and in fact, both ethanol and lactate are waste products. So why do cells run fermentation reactions? Photosynthesis video and chapter 5. (2) Why are plants green? 6. (2) What is the source of the electrons in the electron transport chain in the chloroplast? And where do the electrons end up once they pass through the chain? 7. (4) In hot and dry climates, plants face extra challenge... when their stomata are open, plants can do the gas exchange they need for photosynthesis, but they also lose water. However, closing stomata to prevent water loss causes the internal levels of CO2 to fall. and this presents a problem because when plants run out of CO2, the enzyme RuBisCO will bind oxygen instead in a process called photorespiration. Define photorespiration and explain the two main strategies plants use to prevent it (they are called C4 plants and CAM plants).Explanation / Answer
According to chegg guidelines i am answerring the very first question.
Dinitrophenole are uncouplers and these are able to inhibit oxodative respiration process. In the respiration process ATP is produced by the use of protons. These protons are present in mitochondrial matrix with higher concentration. They moves towards the Perimitochondrial membrane by the process of proton pumping. This Proton pumping process is responsible for the formation of ATP. Pores which are generated by dinitrophenol makes protons to transfer into Peri mitochondrial membrane which leads to reduction in Proton concentration in mitochondrial matrix. reduced Proton concentration in mitochondrial matrix leads to production or blockage of ATP formation process.
