Which of the following correctly describes lactic acid fermentation and alcohol fermentation?
Which statement correctly describes the difference between alcohol fermentation and lactic acid fermentation? Lactic acid fermentation produces lactate, and alcohol fermentation produces ethanol.
What are the similarities between lactic acid and alcoholic fermentation?
The similarity is that they both happen under anaerobic conditions and produce a little amount of ATP. The difference is that alcoholic fermentation gives CO2 while lactic acid does not.
What occurs in lactic acid fermentation?
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution.
What are the similarities and differences between cellular respiration and fermentation?
That is, cellular respiration takes place in the presence of oxygen, while fermentation takes place in the absence of oxygen. Cellular respiration is a more energy-productive process and generates 34 molecules of ATP. In comparison, fermentation generates only 2 molecules of ATP.
What is the difference between lactic acid fermentation and alcoholic fermentation quizlet?
Lactic Acid Fermentation is a form of anaerobic respiration. … The product of lactic acid fermentation is lactic acid, but the products of alcoholic fermentation is ethanol and Co2. The main difference between aerobic and anaerobic is the presence of O2.
What is the purpose of lactic acid and alcoholic fermentation?
When exposed to oxygen, lactic acid molecules break down into carbon dioxide and water. When used in food production, this lactic acid breaks down sugars, preventing food from spoiling. Alcohol fermentation can take place in environments both with and without oxygen, with differing results.
Does alcoholic fermentation occur in humans?
Humans cannot ferment alcohol in their own bodies, we lack the genetic information to do so. … Many organisms will also ferment pyruvic acid into, other chemicals, such as lactic acid. Humans ferment lactic acid in muscles where oxygen becomes depleted, resulting in localized anaerobic conditions.
Why can yeast make alcohol but human muscles make lactic acid?
When yeast cells are kept in an anaerobic environment—an environment without oxygen—they are forced to ferment sugar and other foods. In contrast to fermentation in your muscle cells, fermentation in yeast produces alcohol, instead of lactic acid, as a waste product (Figure 7-23). … The alcohol evaporates during baking.
