Question 5 Different glycoproteins can have a diverse array of oligosaccharides. Which of the statements below about this diversity is TRUE? Oligosaccharide diversity comes from modifications that occur in the ER of the 14-sugar oligosaccharide added to the protein in the ER. A diversity of oligosaccharyl transferases recognizes specific protein sequences, resulting in the linkage of a variety of oligosaccharides to proteins. Different oligosaccharides are covalently linked to proteins in the ER and the Golgi. Extensive modification of oligosaccharides occurs in the extracellular space. 1 pts

Which of the following is not an example of a two-part pricing scheme in the context of price discrimination? A customer pays full price for the first 10 copies of a software program and then receives a 10 percent discount on each additional copy it buys. A customer pays a $10 cover charge to enter a bar and then pays $5 for each beverage. An amusement park charges an admission fee and then charges a per unit price for each of the rides offered by the park. A firm, e.g., Sam's Club or Costco, charges a membership fee that is separate from the price paid for items purchased from the firm.

You have been asked to design an "Aerobic degradation reactor"for industrial wastewater effluent of 1000 m/h,that is containing of benzoic acid(2000 ppm) and ethanol(900 ppm)by a mixed culture of microorganisms.Assume both microorganisms having similar compositions and utilizing oxygen and ammonia as main nutrients. Submit a report showing the followings 1.The bio-reaction stoichiometry for both substrates in the mixture 2.Calculate RQ.CO2 and biomass yields if Benzoic Acid degradation rate equal microorganism growth rate 3.What will be the volume of the continuous bioreactor if the m for benzoic acid degradation=1/h and K=1000 ppm. 4. Find the optimum dilution rate (optimum =maximum mixed substrate reduction)
