Both D-glucose and maltose (a disaccharide composed of two glucose residues) can be used as carbon sources by Escherichia coli. However, D-glucose is taken up by an example of the sugar phosphotransferase system and maltose is taken up by an example of an ABC transporter system. What are the differences between these systems? What are their protein components? What is the source of energy for accumulation of the sugar against a concentration gradient? In which form does the sugar appear in the cell?

Expert Solution

Both system has been explained in attached image below . Hope this will help.

here maltose as such appear in the cell with out addition of any group.

2. Sucrose is a disaccharide composed of glucose and fructose linked together. Hydrolysis of sucrose results in an equimolar solution of glucose and fructose. The specific rotation of sucrose is +66.5. If a solution of sucrose is completely hydrolyzed by strong acid how would you expect the optical rotation of the solution to change? Justify your answer. 3. If a mixture was made using 15 g of D-glucose and 15 g of L-glucose in 100 mL of water, what would...

the compound dimethyl phthalate, used in insects repellants, is composed of carbon, hydrogen, and oxygen and has a molar mass of 194.2 g/mol. A 0.2572 g sample of the compound was burned in a combustion apparatus and 0.583 g of CO2 and 0.119 g of H2O were collected. What is the molecular formula of dimethyl phthalate?

Glycogen phosphorylase and the sodium-potassium pump both have amino acid residues that can be phosphorylated. In the case of the sodium-potassium pump it is Asp369. In glycogen phosphorylase, it is Ser14 that gets phosphorylated. Compare and contrast the role of phosphorylation for both proteins with regards to how the proteins function.

There are two factories in a small town. Both of them emit carbon dioxide into the air. Factory 1 currently emits 120 tons per month, whereas factory 2 currently emits 160 tons per month. The technology of each factory is different, so their costs of reducing emissions are different as well. The tables below show the costs of reducing emissions in increments of 20 tons per month for each factory: Factory 1 Total cost of reducing emissions by 20 tons/month...

The can industry is composed of two firms. Suppose that the demand curve for cans is P= 100- Q and the total cost function of each firm is TC = 2 + 15q. b) If only one firm enters a new market, how much will each firm produce and will make the profit? c) If both enter the new market, how much will each firm produce and will make the profit? e) If these two firms collude and they want...
