Bacteroides is the predominant genus of
bacteria found in the human gut
microbiota. As anaerobic bacteria,
Bacteroides undergo fermentation in the
gut, converting otherwise nondigestible
carbohydrates into fermentation
products that are used by the host for
energy. Which of the following toxins
would be most likely to disrupt
carbohydrate metabolism in Bacteroides
species? *
a toxin that inhibits the function of ATP
synthase
a toxin that prevents the formation of
Krebs cycle products
a toxin that inhibits the function of an
enzyme during glycolysis
a toxin that breaks down the membrane
proteins of the electron transport chain
The pathway shown below is used by a fungus to create Arginine from a precursor starter molecule. A nonsense mutation occurs in the gene that encodes enzyme 2. This fungus is grown on media that only contains the precursor. Discuss the effects of this mutation on:(i) The function of Enzyme 2 (ii) The potential of the fungus to produce Ornithine
Plasmodium use digestive vacuoles (DV) to digest hemoglobin and heme from red blood cells into fuel sources for their life cycle. The DV is the site where host proteins are degraded by the parasite and then the peptide pieces are exported into the Plasmodium cytosol for use in biosynthesis. Plasmodium falciparum chloroquine resistance transporter, PfCRT, is a transporter in this DV membrane and its original function was unknown until recently. Researchers digested hemoglobin into peptide fragments and then tested the effect of these fragments on PfCRT function. VF-6-2 is one of these fragments of hemoglobin and apparently a natural substrate of PfCRT. Chloroquine, for which the transporter was originally named, is a substrate only of mutant transporters. One mutant PfCRT, for instance, has K76T in its substrate binding site and thus a significantly lower Km for chloroquine, inspiring the original name of the transporter, because of its importance for drug resistance in malaria…

- Archae are the source of many enzymes used for biocatalysis in diverse industries such as food and feed, pharmaceuticals, detergent, and beverage industries. These enzymes have unique structural and functional properties that enable use under extreme conditions. Use: https://biolres.biomedcentral.com/articles/10.1186/s40659-018-0186-3 for supplemental info What are three classes of extremophiles and their unique growth characteristics? Based on these characteristics, where are they typically found? The functional properties are linked to protein structural characteristics that imparts unique functional properties. For alkaliphiles and thermophiles, what structural elements (or characteristics) within the enzyme structure create these unique properties? See Table 2. Briefly discuss how the unique properties of these enzymes may be beneficial to the design of bioseparation processes. To recover intracellular enzymes, the Archae need to be lysed. Based on their structures,…arrow_forwardWhich one of the following best describes the role of water in the reaction that is catalyzed by chymotrypsin? choose the best answer based on your coverage. Water forms several H-bonds with the transition state to stabilize it. Water deprotonates the Ser, converting Ser into a strong nucleophile. Water is a product of the reaction. His deprotonates the water, converting the water into a strong nucleophile. Water serves as a catalyst, being consumed and then regenerated in the reaction.arrow_forwardTriclosan is a broad-spectrum antibacterial agent used in many household products. It is structurally similar to polychlorobiphenylol, a substrate that binds to the active site of the enzyme sulfotransferase. Based on these facts, you can conclude that triclosan most likely: lowers the activation energy of chemical reactions. functions as an enzyme when sulfotransferase is absent. is a competitive inhibitor. acts as a noncompetitive inhibitor.arrow_forward
- An organism is discovered living near hydrothermal vents deep in the ocean where sunlight cannot reach. It is found to gain energy through the oxidation of inorganic sulfur compounds present in its environment and uses this energy to turn CO2 into complex organic compounds.

Hexokinase catalyzes the transfer of a phosphate group from ATP to glucose to form glucose-6-phosphate. Phosphofructokinase catalyzes the isomerization of glucose-6-phosphate to fructose-6-phosphate. Fructose-bisphosphate aldolase cleaves Fructose-1,6-bisphosphate into two different three-carbon sugars.

- Imagine you are trying to use an organism to remove organic matter in a wastewater treatment plant (i.e., poop). You would like to maximize the amount of waste consumed while also minimizing the amount of cells produced. Assuming these organisms exist and all other things are equal, what combination of chemoorganotrophic organism and environment would make the most sense to use? An organism that only has the Entner-Duoduroff pathway under anaerobic conditions. This was a trick question – the organism would have to be a chemolithotroph since it is consuming a chemical. An organism that only has the Entner-Duoduroff pathway under aerobic conditions. An organism that only has the Embden Meyer Parnas pathway under anaerobic conditions.

Using curved arrows, show the mechanism of each step labeled with a blue letter. Draw out abbreviated structures of the coenzymes, so that you can effectively show all arrow pushing. You may abbreviate the coenzymes by putting R groups on the molecule, but do draw out the parts of the structure that are involved in the arrow pushing. Some of the transformations will require you to show multiple structures to show all of the arrow pushing (particularly some of the coenzyme-mediated steps). You do not need to show specific amino acid residues that perform the catalysis. You can abbreviate acidic amino acid residues “Enz–B–H” and basic residues “B–Enz”.arrow_forward
