- What is the function of the mitochondria? What is the relationship between ATP and ADP? Why is ATP so important in biological systems?Which of the following statements is most correct? The electron transport chain - A: generates a pH gradient that reduces O2 to H2O B: generates a proton gradient across the outer mito membrane C: generates a proton gradient across the inner mito membrane D: uses the energy stored in high energy electron carriers to synthesize ATP E: establishes a membrane potential across the outer mito membraneCells can make ATP through aerobic respiration, anaerobic respiration, or fermentation. Which of the following pathways do all three forms of cellular catabolism share? breaking down pyruvate into CO2 through a series of steps reducing pyruvate into lactic acid or acetaldehyde to regenerate NAD+ breaking down a molecule of glucose or other organic fuel into two molecules of pyruvate passing electrons through a chain of proteins to an electronegative molecule to oxidize NADH
- In the Electron Transport Chain, how are hydrogen ions pumped out of a bacteria cell and then how do they get back into the cell? How does this process create adenosine triphosphate (ATP)? View keyboard shortcutsLook at the figure below and answer the following questions. The organelles shown are called [Select] The locations within the organelle are identified by letters J- N. The letter O means other or not shown.. In [Select] synthesis (carbon fixation) taking place. In [Select] concentration of protons H+ In L you would find the light harvesting photosystems embedded. In N you would find a ATP synthase embedded. In [Select] J. Outer membrane. K. Inner membrane- L. Thylakoid you would find carbohydrate V membrane transport system with a proton pump embedded. M. Lumen- N. Stroma.- you would find a higher you would find a short electronHow is the function of the thylakoid membrane similar to that of the inner mitochondrial membrane?
- How does DCPIP act as an indicator of presence of mitochondria? Will mitochondria in the presence of DCPIP still make ATP? Why or why not?A human sperm cell moves its flagella back and forth in order to move through its environment. Which statement describes how this eukaryotic cell transfers energy to the flagellum in order to allow it to move? The cell uses photosynthesis to make the glucose needed to create ATP. The cell uses the mitochondria to generate high energy proteins that move the flagella. The cell mitochondria utilize cellular respiration to generate glucose that gives the flagella energy to move. The cell produces ATP in the mitochondria and the breaking of high energy bonds are used to move the flagella.is there other ways of organisms obtaining energy from ATP? Mostly all biological processes uses ATP why can't they use ADP, GTP, or UTP? Why did all organisms favor ATP as their main energy source? What are some causes/diseases of the mitochondria failing to produce ATP?
- How does cellular respiration differ in prokaryotes and eukaryotes?1. Eukaryotes perform reactions in mitochondria; prokaryotes use the plasma membrane. 2. Eukaryotes use substrate-level ATP synthesis; prokaryotes use oxidative phosphorylation.3. Eukaryotes do not use oxygen; prokaryotes only use oxygen. 4. Eukaryotes use NAD+/NADH as electron acceptors; prokaryotes use FAD+/FADH2.Figure 7.11 Dinitrophenol (DNP) is an "uncoupler" that makes the inner mitochondrial membrane "leaky" to protons. It was used until 1938 as a weight- loss drug. What effect would you expect DNP to have on the change in pH across the inner mitochondrial membrane? Why do you think this might be an effective weight-loss drug? Intermembrane space Mitochondrial matrix ATP Synthase ADP Inner mitochondrial membrane ATP Figure 7.11 ATP synthase is a complex, molecular machine that uses a proton (H) gradient to form ATP from ADP and inorganic phosphate (Pi). (Credit: modification of work by Klaus Hoffmeier)You treat cells with 2,4 dinitrophenol (DNP). This compound creates a temporary channel in the inner membrane of the mitochondria though the protons can move. Which of the following would you observe in these cells? Select all that apply The cells do not synthesize ATP in the presence of DNP The cells synthesize ATP in the presence of DNP The cells reduce oxygen in the presence of DNP The cells generate carbon dioxide in the presence of DNP
