The correct answer is C) There is not enough oxygen in the culture medium. This is because of alcoholic fermentation, and anaerobic process where the yeast transform sugar (glucose) in ethylic alcohol (ethanol) and carbon dioxide. Glucose is decomposed into pyruvic acid which then after turns into CO2 and ethanol. The bubbles described, are produced by the carbon dioxide.
The yeast, as well as some bacteria, use the glucose molecule through "glycolysis" to obtain a 3-carbon molecule called pyruvates. Glycolysis consists of 10 coupled reactions, in the end, from one glucose (6 carbons) the yeast will obtain two pyruvates (3 carbons each).
Pyruvate can follow three main routes to obtain ATP, end up as lactate, as carbon dioxide (CO2) and water or as ethanol (alcohol) and CO2. Regarding yeast, it can only be used to obtain Ethanol plus CO2 or to obtain CO2 plus water.
The path that follows from here depends on the reaction medium. The cell gets much more energy (38 molecules of ATP) by converting pyruvate into water + CO2 than by turning it into ethanol + CO2 (2 molecules of ATP). Then, whenever possible, the yeast will follow the CO2 + water path. To support this route the cell needs oxygen. In this case, the cell obtains its energy by breathing when there is no oxygen available, the yeast has a way that allows it to gain much less energy but allows it to survive, the alcoholic fermentation, previously mentioned.
Therefore, A, B, and D answers are wrong for the reasons mentioned above.
No, it would not. This is because any hurricane always loses strength after coming onto land. I don't know if I explained it well but I hope this helps!
The famous composition duo that existed in history and work to create an operettas that is very famous are Gilbert and Sullivan.
- Operetta can be regarded as a form of theatre as well as a genre of light opera. This concept entails spoken dialogue as well as songs
- Gilbert and Sullivan were men that work hand in hand to create influential operettas in history.
- They were a famous Victorian-era theatrical that engaged in partnership of dramatist , they work hand in hand to achieve a great fit around 1830s.
Therefore, Gilbert and Sullivan are great men in operetta world
