Photosystem I (in the green sulfur bacteria) uses either dim underwater volcanic light or dim sunlight to strip away electrons (and protons) from which of the following substrate molecules? C6H12O6, H2O, and CO2 only CO2 only C6H12O6, and H2S only D. H2S only CO2 and H2O only
During aerobic respiration, in heterotrophic organisms, which of the following is a substrate molecule that will be oxidized as it is converted into product molecules? diatomic oxygen carbon dioxide glucose water CO2
You have isolated a bacterium which is a strict, obligate aerobe. You expose the bacterium to oxidative phosphorylation uncouplers. What will first happen to the bacterium, if anything? O electron transport by the ETC will stop O nothing will happen to the bacterium O the proton gradient will be diminished thus reducing ATP synthesis O proton pumping will stop
Having now learned how to conduct basic cell culture, you are ready to complete your first experiments. Below is a portion of the respiration pathway in O.Extremus in which electrons are transferred from NADH to O2; the energy of this reaction is coupled to the pumping of H+, and ultimately ATP production. O.Extremus displays abnormally high activity levels of an enzyme called ATPase. This results in increased hydrolysis of ATP to ADP and later AMP. What effect would this have on the overall metabolic rate in these cells? Explain your reasoning.
4. REDOX reactions in special organelles are like biological batteries. They involve electrons moving through a contained system, and use a build up ions on one side of a membrane to create energy. Energy carrier molecules, electron transport, ATP hydrolysis and ATP synthesis have been common terms over the past month or so. Below is an image that shows two organelles we have been focusing on, along with important membranes that can establish a proton gradient. Using the diagram, explain how chemiosmosis is established in mitochondria and chloroplasts. You must correctly name the important membrane in each organelle, and include the following words in your answer; ATP, protons/, Pi, ATP synthase, ADP, and proton-motive force. Intermembrane High H Thylakoid Lumen Space concentration Electron OLO Transport Chain | 3000 ADP. P SATP H Low H' Matrix concentration Stroma Mitochondrion Chloroplast
