[EX Q]: Sometimes cells need to obtain energy from sugar, but there is no oxygen present to complete cellular respiration. In this situation, cellular respiration can be anaerobic, occurring in the absence of oxygen. In this process, called fermentation, only the first step of respiration, glycolysis, occurs, producing two ATP; no additional ATP is produced. Therefore, the organism only obtains the two ATP molecules per glucose molecule from glycolysis. Compared to the 36-38 ATP produced under aerobic conditions, anaerobic respiration is not a very efficient process. Fermentation allows the first step of cellular respiration to continue and produce some ATP, even without oxygen. Yeast (single-celled eukaryotic organisms) perform alcoholic fermentation in the absence of oxygen. The products of alcoholic fermentation are ethyl alcohol (drinking alcohol) and carbon dioxide gas. This process is used to make common food and drinks. For example, alcoholic fermentation is used to bake bread. The carbon dioxide bubbles allow the bread to rise and become fluffy. Meanwhile, the alcohol evaporates. In wine making, the sugars of grapes are fermented to produce wine. The sugars are the starting materials for glycolysis. Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Pictured below are some products of fermentation ( Figure 1.1). Products of fermentation include cheese (lactic acid fermentation) and wine (alco- holic fermentation). Behind every fart is an army of gut bacteria undergoing some crazy biochemistry. These bacteria break down the remains of digested food through fermentation, creating gas in the process.

[EX A]: lactic acid fermentation is used to make which of the following products?

[EX Q]: Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy. "Our most important finding was the difference between Canadians and the others," said Professor Michel Claes,the lead author of the study."Canadians focus on independence and negotiation.On the other hand,Italians,for example,exercise more control.We found Canadians seem to focus on negotiation in case of a conflict." Claes said Canada,France and Italy were selected for the study because they share important cultural and social factors."We chose FrenchCanadians because they share the same language as France,and originally came from France and share certain values.Italy was included because it was considered to have similar,strong and important family values," he explained. The researchers examined the emotional ties between parents and their children by questioning 1,256 students aged 11 to 19 years old. Canadian students reported less control and more free actions,according to the study.Italian parents were stricter and French parents were somewhere in the middle. Claes explains that the differences lie in education in Canada,France and Italy. "North America has its own educational values,which promote individualization.Tolerance and comprehension are encouraged.Italy,on the other hand,promotes respect of authority,control,and the need for permission." he said. Children from all three countries described their mothers as warm and communicative.Italian and Canadian children had similar feelings about their fathers,and reported high levels of emotional ties.But French fathers were generally thought by their children to be more distant and cold. "We were surprised by this," Claes admitted."It seems as though the relationships between French mothers and their children were becoming closer over time,while fathers maintain a form of distance and coldness,which is more of a source of conflict in France than in the other countries."
[EX A]: According to Michel Claes,what mainly leads to the differences in parentchildren relationships among Canada,France and Italy?

[EX Q]: During the major economic depression of the early 1890s, the Pullman Palace Car Company cut wages in its factories. Discontented workers joined the American Railway Union , led by Eugene V. Debs, which supported their strike by launching a boycott of all Pullman cars on all railroads. ARU members across the nation refused to switch Pullman cars onto trains. When these switchmen were disciplined, the entire ARU struck the railroads on June 26, 1894. Within four days, 125,000 workers on twenty-nine railroads had people quit work rather than handle Pullman cars. Strikers and their supporters also engaged in riots and sabotage. The railroads were able to get Edwin Walker, general counsel for the Chicago, Milwaukee, and St. Paul Railway, appointed as a special federal attorney with responsibility for dealing with the strike. Walker went to federal court and obtained an injunction barring union leaders from supporting the boycott in any way. The court injunction was based on the Sherman Anti-Trust Act which prohibited "Every contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the several States". Debs and other leaders of the ARU ignored the injunction, and federal troops were called into action. The strike was broken up by United States Marshals and some 2,000 United States Army troops, commanded by Nelson Miles, sent in by President Grover Cleveland on the premise that the strike interfered with the delivery of U.S. Mail. During the course of the strike, 13 strikers were killed and 57 were wounded. An estimated $340,000 worth of property damage occurred during the strike. Debs went to prison for six months for violating the federal court order, and the ARU disintegrated.
