question:
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.

lactic acid fermentation is used to make which of the following products?

question:
You love Jay Chou's songs and you can sing some quite well. So you make a video of your performance and post it online for your friends to see. But what if this led to something beyond your wildest imagination--a career in music? Canadian teenager Justin Bieber, 16, has just had the magical experience: He posted homemade videos of his versions of songs by American singer Chris Brown online for his relatives. He received a phone call from Brown, telling him how much he liked his performance. His singing eventually earned him a fan base and a record contract. After releasing a popular record in November 2009, his album My world 2.0 came out last Tuesday. Bieber sings ballads and songs about puppy love. But is he just another gooey teen idol? David Malitz, a columnist with the Washington Post, doesn't think so. "If we truly want the best forAmerican children, let us pause and give thanks for Justin Bieber," he writes. "After years of humdrum bubblegum from Miley Cyrus and the Jonas Brothers, the 16yearold has thrown a candycoated wrench into Disney's heartthrob assembly line by giving young fans something worth screaming their lungs out for lovable pop songs." From a boy who grew up below the poverty line with his divorced mom to a star who caused nearriots in shopping malls, even Bieber himself can't believe his overnight fame, although his kind of success is becoming more and more common in the Internet era. Interested in hockey, the national sport of Canada, the boy once put up pictures of players on the walls of his bedroom. He dreamed of being a hockey star and used to practice signing his autograph. He doesn't need practice now. He signs autographs, if the girls can get close enough, as a music star.

What's Justin Bieber's hobby?
